Intruder.io: The Lean Security Team's Secret Weapon

A 15-person startup taking on vulnerability management giants with a unified platform approach

In a crowded cybersecurity market dominated by legacy giants, Intruder.io is betting that lean security teams don't need more tools—they need smarter ones. With just 15 employees generating $1.8M in revenue, this UK-based startup is proving that unified exposure management can be both powerful and accessible.

"Intruder.io isn't just another scanner—it's a unified command center for security teams drowning in fragmented tools."

Built for the Understaffed

With only 15 employees, Intruder.io understands the pain of lean security teams firsthand. Their platform consolidates vulnerability management, attack surface monitoring, and cloud security into a single interface. This isn't enterprise bloat—it's surgical precision for teams that can't afford to juggle five different security tools.

The SEO Growth Engine

Intruder.io's traffic strategy is a masterclass in targeting high-intent keywords. They rank for terms like 'owasp zap' (40K monthly searches) and 'pentester' (39K searches), positioning themselves directly in the path of security professionals actively seeking solutions. With 49% organic traffic, they're not buying attention—they're earning it through content that speaks to real security challenges.

The company's tech stack reveals a modern, agile approach. Built on jQuery, Tailwind CSS, and Bootstrap, it's a pragmatic choice that prioritizes speed and maintainability over flashy frameworks. This aligns perfectly with their target audience: security teams who value substance over style and need tools that work, not tools that wow.

  • Unified platform approach: Vulnerability management + attack surface monitoring + cloud security in one place
  • Lean team efficiency: 15 people generating $1.8M in revenue (120K per employee)
  • High-intent SEO strategy: Capturing security professionals actively searching for solutions
  • Modern tech stack: Pragmatic choices that prioritize speed and reliability

The Lean Security Revolution Has Arrived

Intruder.io proves that in cybersecurity, focus beats scale. For lean teams tired of tool sprawl, this might just be the unified solution they've been waiting for.

Constant Battle with Account

The dashboard is great and intuitive. However, every other time I tried to scan a target from a client, my account would get "suspended". I'm tired of trying to fight to keep my account open, not worth the time or money. Plus, the chat bot doesn't give you options to prove you have authority to do the work aside from two options that really have nothing to do with immediate verification. Better solutions than this company are Snyk and Acunetix for the same price or less.

Company Response9/23/2022

Hello Anna, We’re really sorry to see that you had a frustrating experience with the platform and apologise for any inconvenience caused. If you would like to revisit Intruder, you’re more than welcome to reach out via [email protected] and a member of the team would be delighted to assist you. To address your feedback specifically, a member of the team took a look at you account and identified a couple of reasons for the suspension: 1. The account name (or company name) was set to ‘Student’ and since we don’t support academic use, the account was flagged. 2. The two targets you added didn’t correlate with the email domain used to sign-up (which can be indicative of a user scanning other people’s property). Both of these can trigger a suspension and when that happens an email is automatically sent explaining the situation and how it can be resolved. We were able to confirm that an email was delivered, though we understand that sometimes they do get missed. We believe this may have also happened to an email that was sent by a member of commercial team offering a call. As for the bot, it offers two options for establishing a user’s authority to scan a target, both of which connect you with a member of the team as they’re the ones that can manually verify this and reverse the suspension. We were only able to find one interaction between yourself and the bot, but as you didn’t click any of the options it automatically closed after three minutes. (Though you can reopen a ticket at anytime by replying or clicking a button). We weren’t able to find any other correspondence from you, but if we have missed anything, please don’t hesitate to let us know so we can investigate and hopefully improve our processes. We look forward to hearing from you soon. Kindest, Team Intruder
