The cybersecurity industry is growing fast, with both new and established players competing for attention. Many new AI-led security innovations are also sweeping the market.
Using Ahrefs’ website growth data, we’ve found the 40 fastest-growing cybersecurity companies of 2025 based on estimated year-over-year (YoY) organic traffic growth.
We analyzed 4,300+ global cybersecurity companies and filtered for those with at least 1,000 monthly organic visits in 2025.
Only companies that grew organic traffic at least five times compared to the previous year made the final list.
The top 40 fastest-growing cybersecurity companies fell into a few key categories:
- Cloud and SaaS security: Protecting modern infrastructure, apps, and user data in the cloud.
- Threat detection and response: Identifying and mitigating cyber threats in real time.
- Identity, access, and privacy: Managing credentials, encryption, and secure communications.
- Developer and API security: Safeguarding APIs, integrations, and developer environments.
- Training, services, and compliance: Strengthening security through education, audits, and risk management tools.
Thanks to AI, many innovations are happening in the cybersecurity industry right now, leading to the rise of new players entering the market in the last year or two. I’ve cherry-picked five companies using innovative or different strategies to grow incredibly quickly.
Here’s what working for each of them.
Akto is a fast-growing API security platform that caters to technical teams like software developers, QA engineers, and automation specialists.
Their standout growth (a 45x increase in organic traffic since 2024) is largely driven by a library of free developer tools, such as phone number generators, regex testers, and email validators.
These tools now account for nearly 98% of Akto’s organic traffic.
But what makes this strategy particularly effective is its resilience against AI Overviews. The keywords their tools rank for feature AI Overviews half as often as the rest of the keywords they rank for.
| Akto’s keywords with AI Overviews | |
|---|---|
| Whole Site | 13.4% |
| Tools | 7.3% |
That means searchers are far more likely to click through to Akto’s site to access the tools directly, rather than getting their answer from an AI response.
Since the tools they’ve created are aimed specifically at the audience likely to buy their product, it’s an effective mid-funnel content strategy that can also improve their brand awareness. They’re not just chasing traffic to boost their vanity metrics.
Wiz is a cloud security platform that helps organizations identify and remediate risks across their entire cloud environment. It experienced fast growth in 2024:
Their growth (over 7x year-over-year) was driven largely by the success of their Wiz Academy, an educational resource center tailored to technical security professionals.
Despite having a similar number of pages as their blog, the Academy outperforms it dramatically across every metric:
- Earning 47.4% of the site’s total traffic
- Generating 15x more traffic value per page than the blog
- Ranking for 3,500+ more keywords
- Requiring significantly fewer links to perform
| Academy | Blog | |
|---|---|---|
| Pages | 343 | 393 |
| Keywords | 17618 | 14061 |
| Organic traffic | 45987 | 5072 |
| Traffic value | $220,000 | $16,500 |
| Links | 6904 | 53,035 |
| Referring domains | 1868 | 5072 |
| Average traffic value / page | $641 | $42 |
These educational pages rank for high-intent, technical keywords and are structured in a way that still encourages clicks (even from AI Overviews) by delivering expertise, clarity, and trust.
By investing in authoritative, curriculum-style content rather than just publishing isolated blog posts, Wiz has built a scalable, brand-owned learning hub that positions them as a trusted thought leader, not just a vendor.
Managed Methods is a cybersecurity platform focused on protecting K–12 schools from cyber threats, data loss, and compliance issues.
It grew over 7x in 2024 at a steady and sustainable pace:
While many cybersecurity companies chase high-volume, technical blog topics, Managed Methods took a more focused route by creating educational content specifically for school administrators and educators.
Their blog is the highest performing segment on their website earning over 92% of traffic. But it doesn’t try to rank for advanced cybersecurity concepts.
Instead, it covers practical education topics, like securing student data in Google Workspace and managing technology in the classroom. This particular focus has helped them grow steadily and build trust within a niche audience that most security vendors underserve.
Many other companies I checked out when curating this list of fastest growing cybersecurity companies experienced unsustainable growth from one or two viral posts. Managed Methods stands out for having a clear, repeatable blog content strategy.
Their growth is grounded in relevance (not luck), which positions them well for long-term visibility and authority in the education sector.
Edge Delta offers observability and log analytics tools for engineering teams managing modern infrastructure at scale.
Their traffic began ramping up in April 2024 and has since grown nearly 19x, driven primarily by a surge in high-performing technical blog guides.
Over 94% of their organic traffic comes from blog posts focused on engineering-centric topics — the kind that AI Overviews struggle to replicate with accuracy.
In fact, 21.5% of the keywords they rank for trigger an AI Overview which is fairly high, especially when we compare it to Akto’s keywords that feature AI Overviews 13.4% of the time at most.
However, Edge Delta’s content depth and specificity give technical readers who require accurate knowledge a reason to click through anyway.
What sets their strategy apart is sustainability. Like Managed Methods, their blog’s performance is distributed across many topics instead of one or two viral posts. They’ve built a library of valuable resources that solve real problems for a high-intent audience — making their SEO strategy both resilient and revenue-aligned.
Stream Security is a cloud detection and response platform helping teams secure dynamic environments through continuous monitoring and real-time policy enforcement.
Their organic growth (over 7x since 2024) is powered by a technical content strategy that answers precise engineering and security questions in-depth.
They structure it as a content hub sharing technical rules:
Rather than relying on broad or news-driven content, Stream Security publishes niche rule sets, configuration guides, and implementation tutorials.
These resources directly align with the daily challenges of their core audience: cloud engineers and security practitioners.
Roughly 20% of the keywords they rank for trigger AI Overviews, but in this case, the technical complexity works in their favor as the need for accurate information by their target audience is quite high.
Their audience isn’t just looking for quick summaries — they need precision, context, and expertise. By owning those queries with high-trust, actionable content, Stream Security earns qualified traffic and builds credibility in a space where correctness matters more than convenience.
Final thoughts
The cybersecurity companies on this list aren’t just growing fast, they’re growing smart.
Each company has found a sustainable path to organic visibility, from developer tools and technical academies to niche content strategies targeting overlooked audiences. They share a deep understanding of their ideal customer and a content approach that delivers value AI can’t easily replace.
In an era where AI Overviews threaten to flatten traffic to generic content, these companies show that depth, specificity, and audience alignment still win.
The fastest-growing cybersecurity companies of tomorrow will be those that create with intent, not just for clicks, but for trust.
