We analyzed thousands of cybersecurity companies and ranked them by a metric that's hard to fake: how fast their organic search traffic grew over the last year. Rising organic traffic is a strong signal of real momentum, because it reflects growing awareness, demand, and a product people are actively looking for.

The cybersecurity market is enormous and still growing fast. It was estimated at $271.9 billion in 2025 and is projected to reach $663.2 billion by 2033, as rising threats push organizations to spend more on security every year.

AI is reshaping where that money flows: investors are pouring capital into AI-native security startups even as overall deal counts tighten, according to PitchBook's cybersecurity VC coverage, which makes fast-growing organic demand the clearest sign of a security company actually breaking out.

So the question we set out to answer is: which cybersecurity companies, across every category from cloud and application security to identity, threat detection, and developer security, are pulling in real, fast-growing organic demand right now?

Sidenote


We rank these companies by how much their organic search traffic grew over the past year: we compare each site's estimated monthly organic traffic now against twelve months ago, using Ahrefs. Organic traffic growth is a strong signal of real momentum because it reflects rising awareness and demand for a product people are actively searching for. To keep the percentages honest we only include companies that already had a real traffic base a year ago, so a jump from a handful of visits doesn't top the list. All data is from Ahrefs.

The 25 fastest growing cybersecurity companies

Below are the cybersecurity companies whose organic search traffic grew fastest over the past year, ordered from the steepest growth down, each with a traffic snapshot, the key numbers, and a short read on what's driving the momentum.

1. Silent Push (+700%)

Line chart of estimated monthly organic search traffic for Silent Push, rising, reaching about 10.5K visits a month over 1 year (a change of +700%).
  • Organic traffic growth (1-year): +700%
  • Organic traffic (monthly): 10.5K
  • Year founded: 2018
  • Location: Reston, United States

What they do

Silent Push is a threat intelligence platform that helps security teams identify and track adversary infrastructure before attacks are launched, used by threat hunters, SOC analysts, and enterprise security operations teams.

Silent Push is the fastest growing company on this entire list, which makes its +700% traffic climb worth paying attention to. Proactive threat intelligence, where you map attacker infrastructure *before* you're hit rather than responding after, is a category that's been gaining real traction as security teams shift from reactive to predictive operations, and Silent Push appears to be capturing a large share of that rising search demand.

2. Huntress (+680%)

Line chart of estimated monthly organic search traffic for Huntress, rising, reaching about 350K visits a month over 1 year (a change of +680%).
  • Organic traffic growth (1-year): +680%
  • Organic traffic (monthly): 350K
  • Year founded: 2015
  • Location: Columbia, Maryland, USA

What they do

Huntress is a managed security platform built specifically for small and mid-sized businesses and the managed service providers that serve them, combining threat detection, endpoint protection, and 24/7 human-led response in one service.

In June 2024, Huntress announced a $150 million Series D led by Kleiner Perkins, Meritech Capital, and Sapphire Ventures, bringing its total disclosed equity funding to well over $200 million.

One of the more established names on this list, Huntress has been building since 2015, but its organic traffic growth over the past year tells a very current story. SMBs are increasingly seen as soft targets by ransomware groups, and demand for security that's actually designed for that market (rather than scaled-down enterprise tools) is growing fast, with Huntress pulling in around ~350K monthly visitors to prove it.

3. Framework Security (+440%)

Line chart of estimated monthly organic search traffic for Framework Security, rising, reaching about 3K visits a month over 1 year (a change of +440%).
  • Organic traffic growth (1-year): +440%
  • Organic traffic (monthly): 3K
  • Year founded: n/a
  • Location: Austin, United States

What they do

Framework Security is a cybersecurity consulting and managed services firm based in Austin that helps organizations build and improve their security programs, covering areas like penetration testing, compliance, and security strategy.

Funding is not publicly disclosed.

Framework Security's +440% traffic growth is a strong signal for a consulting-led security firm, where organic reach is typically much harder to build than it is for product companies. The jump suggests a content and SEO strategy that's resonating, pulling in searches around compliance, risk, and security program building at a time when organizations of all sizes are under pressure to formalize their security posture.

4. PC Matic (+300%)

Line chart of estimated monthly organic search traffic for PC Matic, rising, reaching about 100K visits a month over 1 year (a change of +300%).
  • Organic traffic growth (1-year): +300%
  • Organic traffic (monthly): 100K
  • Year founded: n/a
  • Location: Sioux City, United States

What they do

PC Matic is an endpoint security and antivirus software provider that uses an application allowlisting approach to block malware, used by consumers, small businesses, and U.S. government agencies.

PC Matic hasn't announced any outside equity funding.

PC Matic is one of the bigger brands on this list by monthly traffic, and a +300% traffic jump at that scale is a serious result. Allowlisting-based endpoint security has been getting renewed attention as signature-based approaches struggle to keep pace with modern threats, and PC Matic's positioning around Made-in-America software and government contracts appears to be bringing in a much wider search audience than before.

5. Xygeni (+290%)

Line chart of estimated monthly organic search traffic for Xygeni, rising, reaching about 30.5K visits a month over 1 year (a change of +290%).
  • Organic traffic growth (1-year): +290%
  • Organic traffic (monthly): 30.5K
  • Year founded: 2021
  • Location: Madrid, Spain

What they do

Xygeni is an application security platform that protects the software supply chain, scanning code, open-source dependencies, and CI/CD pipelines for vulnerabilities, leaked secrets, and malicious packages.

In July 2023, Xygeni announced a €4 million investment led by Spanish software investor Investing Profit Wisely (IPW).

Software supply chain attacks have turned open-source dependencies into one of the most closely watched risks in security, and Xygeni has grown alongside that concern. Its organic traffic has roughly quadrupled in a year to around 30K monthly visits, a big jump for a Madrid company that only launched in 2021.

6. Metomic (+280%)

Line chart of estimated monthly organic search traffic for Metomic, rising, reaching about 21.5K visits a month over 1 year (a change of +280%).
  • Organic traffic growth (1-year): +280%
  • Organic traffic (monthly): 21.5K
  • Year founded: 2018
  • Location: London, United Kingdom

What they do

Metomic is a data security platform for SaaS environments that scans tools like Slack, Google Drive, Jira, and GitHub for sensitive data exposure, used by security and compliance teams trying to get visibility and control over what's being shared across their SaaS stack.

Metomic raised a $20 million Series A in February 2023, led by Evolution Equity Partners, with participation from Resonance and Connect Ventures.

The wave of SaaS adoption over the past few years has left a lot of organizations with sensitive data scattered across dozens of tools they don't fully monitor, and Metomic is clearly capturing the search demand that's coming with that realization. A +280% jump in organic traffic reflects a category, SaaS data security, that's moving from a nice-to-have to a genuine security priority as regulators and auditors start asking harder questions.

7. Accountable (+260%)

Line chart of estimated monthly organic search traffic for Accountable, rising, reaching about 28K visits a month over 1 year (a change of +260%).
  • Organic traffic growth (1-year): +260%
  • Organic traffic (monthly): 28K
  • Year founded: n/a
  • Location: Fort Worth, United States

What they do

Accountable HQ is a HIPAA compliance management platform that helps healthcare organizations, vendors, and business associates build and maintain their compliance programs, covering risk assessments, policy management, and employee training.

Accountable HQ hasn't announced a major venture round.

HIPAA compliance has always been a pain point, but the combination of increased OCR enforcement activity and a growing market of digital health vendors who need to demonstrate compliance to hospital and health system customers has pushed more organizations to look for purpose-built tools rather than spreadsheets. A +260% traffic increase to around ~30K monthly visitors reflects that shift translating into real search volume.

8. Endor Labs (+160%)

Line chart of estimated monthly organic search traffic for Endor Labs, rising, reaching about 5.5K visits a month over 1 year (a change of +160%).
  • Organic traffic growth (1-year): +160%
  • Organic traffic (monthly): 5.5K
  • Year founded: 2021
  • Location: Palo Alto, United States

What they do

Endor Labs is a software supply chain security platform that helps development and security teams manage open-source dependency risk, detect vulnerabilities in AI-generated code, and enforce policy across CI/CD pipelines.

The rise of AI-generated code has poured fuel on software supply chain security as a category: when developers are shipping code they didn't fully write themselves, the question of what's actually in that code becomes a lot more urgent. Endor Labs has positioned itself squarely in that conversation, and the +160% traffic growth suggests that positioning is pulling in the right audience.

9. OpenCVE (+160%)

Line chart of estimated monthly organic search traffic for OpenCVE, rising, reaching about 4.5K visits a month over 1 year (a change of +160%).
  • Organic traffic growth (1-year): +160%
  • Organic traffic (monthly): 4.5K
  • Year founded: 2019
  • Location: Lille, France

What they do

OpenCVE is an open-source CVE monitoring and alerting platform that aggregates vulnerability data from public feeds and lets security teams filter, subscribe to, and track CVEs relevant to their specific technology stack.

Funding is not publicly disclosed.

Vulnerability management is one of those security functions that every organization needs but many do inconsistently, and OpenCVE's growth suggests there's a real audience for a lightweight, open-source way to stay on top of the CVE firehose without paying for an enterprise platform. A +160% organic traffic increase for an open-source tool with no disclosed marketing budget is a pretty honest signal of genuine utility.

10. MysteriumVPN (+130%)

Line chart of estimated monthly organic search traffic for MysteriumVPN, rising, reaching about 54.5K visits a month over 1 year (a change of +130%).
  • Organic traffic growth (1-year): +130%
  • Organic traffic (monthly): 54.5K
  • Year founded: 2017
  • Location: Zug, Switzerland

What they do

Mysterium VPN is a decentralized VPN built on a peer-to-peer network, where users can both consume and provide bandwidth nodes, used by privacy-focused consumers and developers who want censorship-resistant, non-custodial connectivity.

Funding is not publicly disclosed.

The decentralized privacy infrastructure space has picked up real momentum as trust in centralized VPN providers has eroded amid a string of high-profile no-log policy violations and ownership questions. Mysterium's peer-to-peer model is a genuine architectural differentiator, and the jump to ~50K monthly organic visitors in a single year suggests that audience is growing faster than the broader VPN category.

11. SuperTokens (+120%)

Line chart of estimated monthly organic search traffic for SuperTokens, rising, reaching about 64K visits a month over 1 year (a change of +120%).
  • Organic traffic growth (1-year): +120%
  • Organic traffic (monthly): 64K
  • Year founded: 2020
  • Location: San Francisco, United States

What they do

SuperTokens is an open-source authentication and session management solution that gives developers a self-hostable alternative to managed identity services like Auth0 or Cognito, covering login flows, token handling, and multi-factor authentication.

SuperTokens is backed by Y Combinator.

The open-source auth space has gotten a lot more competitive, but SuperTokens has clearly built a strong content presence to go with its product, reaching ~60K monthly organic visitors in a category where developers are actively researching their options. The +120% growth reflects the continued shift toward self-hosted identity infrastructure among teams who want control over their auth stack and aren't willing to pay Auth0 pricing to get it.

12. Linford & Co (+120%)

Line chart of estimated monthly organic search traffic for Linford & Co, rising, reaching about 77K visits a month over 1 year (a change of +120%).
  • Organic traffic growth (1-year): +120%
  • Organic traffic (monthly): 77K
  • Year founded: n/a
  • Location: Denver, United States

What they do

Linford & Company is an independent auditing firm that specializes in SOC 1, SOC 2, HIPAA, and FedRAMP compliance audits for technology companies and service organizations.

Linford & Company describes itself as independent and free from private equity, external investors, or debt, and no funding history has been identified.

SOC 2 compliance has gone from a niche enterprise requirement to table stakes for any SaaS company selling to mid-market or enterprise buyers, and that shift has created a large, fast-growing pool of organizations searching for auditors they can trust. Linford & Company's ~80K monthly visitors and +120% growth in a single year suggests their content strategy around compliance topics is doing a lot of the heavy lifting in capturing that demand.

13. Cynomi (+100%)

Line chart of estimated monthly organic search traffic for Cynomi, rising, reaching about 11.5K visits a month over 1 year (a change of +100%).
  • Organic traffic growth (1-year): +100%
  • Organic traffic (monthly): 11.5K
  • Year founded: 2021
  • Location: Herzliya, Israel

What they do

Cynomi is an AI-powered virtual CISO platform that enables managed service providers and managed security service providers to deliver strategic cybersecurity guidance and risk management to SMB clients at scale.

In April 2025, Cynomi closed a $37 million Series B led by Insight Partners and Entrée Capital, with continued backing from Canaan, Flint Capital, and S16VC.

The vCISO category is expanding quickly as small and mid-sized businesses face regulatory and contractual pressure to demonstrate security governance they can't afford to staff internally. Cynomi's approach of delivering that through MSPs is a smart distribution play, and a +100% organic traffic increase in the past year suggests the market for AI-assisted security leadership is moving from a concept to something buyers are actively seeking out.

14. Cycode (+100%)

Line chart of estimated monthly organic search traffic for Cycode, rising, reaching about 17.5K visits a month over 1 year (a change of +100%).
  • Organic traffic growth (1-year): +100%
  • Organic traffic (monthly): 17.5K
  • Year founded: 2019
  • Location: Tel Aviv, Israel

What they do

Cycode is an application security posture management (ASPM) platform that gives security and engineering teams unified visibility and control over risks across the software development lifecycle, from code to cloud.

ASPM as a category has been gaining serious traction as organizations realize that point solutions for individual stages of the dev pipeline leave too many gaps, and Cycode has been one of the names helping define what that category looks like. The +100% organic traffic growth to ~20K monthly visitors reflects a market that's starting to search for consolidated application security answers rather than a patchwork of tools.

15. Orca Security (+100%)

Line chart of estimated monthly organic search traffic for Orca Security, rising, reaching about 58K visits a month over 1 year (a change of +100%).
  • Organic traffic growth (1-year): +100%
  • Organic traffic (monthly): 58K
  • Year founded: 2019
  • Location: Portland, United States

What they do

Orca Security is a cloud security platform that provides agentless visibility across AWS, Azure, and Google Cloud environments, used by cloud security and DevSecOps teams to detect vulnerabilities, misconfigurations, and compliance risks without deploying agents.

Orca Security has raised over $840 million in total disclosed funding, including a $550 million Series C extension led by Temasek in October 2021, which also included CapitalG, Redpoint Ventures, GGV, ICONIQ Capital, and Lone Pine Capital among others.

Cloud security is one of the most competitive corners of the market, so a +100% organic traffic increase to ~60K monthly visitors for a platform that's been around since 2019 is a sign that Orca is still growing its share of search demand rather than plateauing. The agentless approach continues to resonate with teams who need visibility fast, without the operational overhead of deploying and managing agents across sprawling cloud environments.

16. Securden (+93%)

Line chart of estimated monthly organic search traffic for Securden, rising, reaching about 9.5K visits a month over 1 year (a change of +93%).
  • Organic traffic growth (1-year): +93%
  • Organic traffic (monthly): 9.5K
  • Year founded: 2017
  • Location: Chennai, India

What they do

Securden is a Privileged Access Management (PAM) platform that helps IT and security teams control access to privileged accounts, manage passwords, and secure remote connections across on-premises and cloud infrastructure.

Securden has raised a total of $11.7 million, including a $10.5 million Series A in April 2022 led by Tiger Global, with participation from Together Fund and Accel.

PAM is a crowded category dominated by some well-funded incumbents, which makes Securden's +93% organic traffic growth over the past year a genuine competitive signal. Enterprise and mid-market buyers are increasingly scrutinizing privileged access as a core part of their zero-trust programs, and Securden appears to be winning a growing share of that research traffic, particularly from teams comparing alternatives to the big-name PAM vendors.

17. Logto (+87%)

Line chart of estimated monthly organic search traffic for Logto, rising, reaching about 52.5K visits a month over 1 year (a change of +87%).
  • Organic traffic growth (1-year): +87%
  • Organic traffic (monthly): 52.5K
  • Year founded: 2022
  • Location: null

What they do

Logto is an open-source customer identity and access management (CIAM) platform that provides authentication, authorization, and user management infrastructure for developers building SaaS and consumer applications.

Funding details are not publicly disclosed.

Logto is one of the younger companies on this list, founded in 2022, which makes reaching ~50K monthly organic visitors in such a short window a notable result. The open-source CIAM space has seen real appetite from developer teams who want full control over their identity stack without being locked into a managed service, and Logto's growth suggests it's becoming a genuine go-to option in that conversation.

18. miniOrange (+86%)

Line chart of estimated monthly organic search traffic for miniOrange, rising, reaching about 59K visits a month over 1 year (a change of +86%).
  • Organic traffic growth (1-year): +86%
  • Organic traffic (monthly): 59K
  • Year founded: 2015
  • Location: Pune, India

What they do

miniOrange is an identity and access management (IAM) provider that offers SSO, multi-factor authentication, and user provisioning solutions for businesses and developers across a wide range of enterprise applications and platforms.

Funding is not publicly disclosed.

miniOrange is one of the more established companies here, building since 2015, and an +86% organic traffic jump to ~60K monthly visitors at that age isn't something you can attribute to early hype. The IAM market has broadened significantly as organizations move away from monolithic identity platforms, and miniOrange's broad integration coverage seems to be pulling in a steadily growing share of that fragmented demand.

19. Apiiro (+78%)

Line chart of estimated monthly organic search traffic for Apiiro, rising, reaching about 5.5K visits a month over 1 year (a change of +78%).
  • Organic traffic growth (1-year): +78%
  • Organic traffic (monthly): 5.5K
  • Year founded: 2019
  • Location: Tel Aviv, Israel

What they do

Apiiro is a cloud-native application security platform that analyzes code, infrastructure, and developer behavior to identify and prioritize security risks across the software development lifecycle, used by security and engineering teams looking to manage risk from code to cloud.

Apiiro raised a $100 million Series B in November 2022, led by General Catalyst, with participation from Greylock and Kleiner Perkins.

The application security space is consolidating around platforms that can connect code-level risk to business impact, and Apiiro's risk-based approach has clearly found an audience as engineering and security teams look for ways to prioritize what actually matters rather than working through an endless backlog of generic findings. The +78% organic traffic growth reflects a buyer market that's getting more sophisticated in how it searches for AppSec solutions.

20. Netify (+66%)

Line chart of estimated monthly organic search traffic for Netify, rising, reaching about 39K visits a month over 1 year (a change of +66%).
  • Organic traffic growth (1-year): +66%
  • Organic traffic (monthly): 39K
  • Year founded: 2015
  • Location: Ottawa, Canada

What they do

Netify is a network intelligence platform that provides deep packet inspection, application identification, and network analytics for ISPs, MSPs, and enterprises managing traffic visibility and security across their networks.

Funding is not publicly disclosed.

Network visibility has gotten more complex as encrypted traffic and cloud-native architectures make traditional monitoring approaches less effective, and Netify's deep packet inspection approach addresses a real gap for the MSP and ISP market that larger enterprise security vendors don't typically serve well. A +66% organic traffic increase to ~40K monthly visitors is a solid signal of growing search demand for that kind of network intelligence capability.

21. SaltyCloud (+49%)

Line chart of estimated monthly organic search traffic for SaltyCloud, rising, reaching about 4K visits a month over 1 year (a change of +49%).
  • Organic traffic growth (1-year): +49%
  • Organic traffic (monthly): 4K
  • Year founded: 2017
  • Location: Austin, Texas

What they do

SaltyCloud makes Isora GRC, an assessment platform that security teams use to run risk and compliance assessments, review vendors, and track remediation in one place.

SaltyCloud is a public benefit company and hasn't publicly disclosed any funding.

Isora is aimed at security teams that have outgrown spreadsheets but don't want a heavyweight enterprise GRC suite, a group that includes many universities and public-sector organizations. SaltyCloud is one of the smallest brands on this list at around 4K monthly visits, but its traffic has grown by about half in a year.

22. Anchore (+46%)

Line chart of estimated monthly organic search traffic for Anchore, rising, reaching about 7K visits a month over 1 year (a change of +46%).
  • Organic traffic growth (1-year): +46%
  • Organic traffic (monthly): 7K
  • Year founded: 2016
  • Location: Santa Barbara, United States

What they do

Anchore is a container and software supply chain security platform that provides software composition analysis, SBOM generation, and vulnerability scanning for DevSecOps teams building and running containerized applications.

Anchore raised a $20 million Series A in January 2020, led by SignalFire.

SBOM (Software Bill of Materials) requirements have shifted from voluntary to mandatory for many organizations selling to the U.S. federal government, and that regulatory push has broadened the market for container security and software composition analysis tools considerably. Anchore has been in this space since 2016, and the +46% traffic growth suggests that maturing regulatory demand is pulling new buyers into a search process that leads them to Anchore's door.

23. Prophet Security (+34%)

Line chart of estimated monthly organic search traffic for Prophet Security, rising, reaching about 1.5K visits a month over 1 year (a change of +34%).
  • Organic traffic growth (1-year): +34%
  • Organic traffic (monthly): 1.5K
  • Year founded: 2023
  • Location: Atherton, United States

What they do

Prophet Security is an agentic AI platform for security operations that automates alert triage, investigation, and response workflows, used by SOC teams looking to reduce analyst workload and speed up response times.

Prophet Security has raised $41 million in total disclosed funding, including a $30 million Series A in July 2025 led by Accel, and an $11 million seed in April 2024 led by Bain Capital Ventures.

Prophet Security is one of the youngest companies on this list, founded in 2023, and a +34% organic traffic increase in that short window reflects a category, agentic AI for SOC operations, that's attracting real buyer interest very quickly. Security teams are under constant pressure to do more with the same headcount, and automated investigation and triage is one of the more credible AI use cases in security right now.

24. Cymulate (+28%)

Line chart of estimated monthly organic search traffic for Cymulate, rising, reaching about 22.5K visits a month over 1 year (a change of +28%).
  • Organic traffic growth (1-year): +28%
  • Organic traffic (monthly): 22.5K
  • Year founded: 2016
  • Location: Rishon LeZion, Israel

What they do

Cymulate is a breach and attack simulation (BAS) platform that lets organizations continuously test their security controls against real-world attack scenarios, used by security teams that want to validate their defenses rather than just assume they work.

Cymulate has raised $141 million in total funding, including a $70 million Series D in September 2022 led by One Peak, with Susquehanna Growth Equity, Vertex Ventures Israel, Vertex Growth, and Dell Technologies Capital participating.

Breach and attack simulation has been gaining ground as security teams face increasing pressure from boards and regulators to *demonstrate* that their controls actually work, and Cymulate's +28% organic traffic growth to ~20K monthly visitors reflects steady, compounding demand in a category that's becoming a standard part of enterprise security validation programs.

25. Vanta (+24%)

Line chart of estimated monthly organic search traffic for Vanta, rising, reaching about 100K visits a month over 1 year (a change of +24%).
  • Organic traffic growth (1-year): +24%
  • Organic traffic (monthly): 100K
  • Year founded: 2018
  • Location: San Francisco, United States

What they do

Vanta is a trust management platform that automates security compliance for frameworks like SOC 2, ISO 27001, HIPAA, and GDPR, used by fast-growing technology companies that need to demonstrate security to enterprise buyers without building a compliance program from scratch.

In July 2025, Vanta announced a $150 million Series D led by Wellington Management, following a Series C led by Sequoia Capital in July 2024.

At ~100K monthly organic visitors and still growing at +24% year over year, Vanta is one of the highest-traffic brands on this list, and that kind of sustained growth at scale is genuinely hard to maintain. Compliance automation has become a must-have rather than a nice-to-have for SaaS companies selling upmarket, and Vanta's ability to keep pulling in new organic search traffic after several years of strong growth is a sign of a category that's still expanding rather than saturating.

Organic traffic growth = growth in estimated monthly organic search traffic over the past year (now vs twelve months ago). Monthly organic traffic = current estimated monthly organic search traffic (Ahrefs). Data: Ahrefs · October 2026.

How to find this data in Ahrefs

You can rebuild this entire analysis yourself in Ahrefs. Here's the short version:

  • Open Site Explorer, enter a company's domain, and look at the Organic traffic graph. The growth over the last year is what we ranked on.
Ahrefs Site Explorer overview showing a company's organic traffic and referring domains
  • Use the Overview to read the current Organic traffic, Referring domains, and Domain Rating shown in the profiles above, and switch the date range to compare year over year.
  • Or skip the manual work and let Letaido run the whole pull, filtering, and ranking for any niche you choose, the same way it built this list.

Final thoughts

What stands out across this list of fastest growing cybersecurity companies is how varied the categories are: supply chain security, agentic SOC, vCISO platforms, open-source identity, decentralized VPN, and compliance automation all show up here alongside more established categories like PAM and cloud security, which is a useful reminder that fresh demand is forming in a lot of corners of the market at once.

The common thread is companies that matched a real, specific security problem to a product people are actively searching for, and then built enough content presence to capture that demand as it grew.

If you're watching where the next wave of cybersecurity investment and adoption is forming, this list of fastest growing cybersecurity companies is a pretty good place to start.
