Intruder AI Pentesting

Overview

Intruder is a London-based cybersecurity company, a graduate of GCHQ's Cyber Accelerator, that provides continuous attack surface management and vulnerability scanning. In April 2026 it launched AI pentesting agents that bring autonomous, pentester-style investigation to its platform, aiming to deliver the depth of a penetration test on demand.

AI Pentesting Agents

In this initial release, the agents actively investigate vulnerability findings surfaced by Intruder's scanner using the same methods a human pen tester or security expert would apply, confirming whether issues are genuinely exploitable rather than leaving teams with a raw list of potential vulnerabilities. The platform unifies attack surface management, vulnerability scanning, and AI-driven investigation in a single interface, with full web application pentesting expected to follow over the subsequent quarter.

Pricing and Plans

Intruder sells four subscription tiers: Essential from $149 per month, Cloud from $299 per month, Pro from $499 per month, and Enterprise with custom pricing. The AI pentesting agents are available on the Cloud, Pro, and Enterprise plans. The company explicitly targets the midmarket, organizations large enough to face serious cyber risk but too small to fund the roughly $50,000 manual pentests and dedicated security teams that enterprises rely on.

Who It's For

Intruder AI Pentesting is a good fit for midmarket and cloud-native teams that need continuous, validated security coverage without a large in-house security function. It is best treated as a force multiplier for triage and validation rather than a full substitute for periodic expert-led manual penetration testing on the most sensitive systems.
