Affordable penetration testing from Revelion starts free, with 10,000 credits and no payment required, and scales to pay-as-you-go top-ups from £10. This is real penetration testing: AI agents that exploit vulnerabilities, chain findings into proven attack paths, and produce proof-of-concept evidence. Not vulnerability scanning. Not signature matching. Actual exploitation.
The price of traditional pentesting has not kept pace with the security needs of most organisations. At £2,000 to £15,000 per engagement, annual testing is a significant budget line. For the businesses that need it most, including fast-growing startups and SMBs with limited budgets, that cost often means no testing at all.
The Difference Between Scanning and Pentesting
This distinction matters before any conversation about price. Vulnerability scanners are not cheap pentesting. They are a different category of tool entirely.
A vulnerability scanner checks your software against a database of known CVEs. It matches signatures, assigns severity scores from a template, and produces a list of software that needs patching. It does not attempt to exploit anything. It does not chain vulnerabilities. It does not distinguish between a theoretical CVSS 9.8 that is blocked by your network segmentation and a CVSS 4.3 that is trivially exploitable in your specific environment.
Revelion's AI agents do what a pentest is supposed to do. They discover attack surfaces dynamically. They attempt exploitation. When they find a vulnerability, they determine whether it leads somewhere: can this IDOR access sensitive data at scale? Can this SSTI be chained to remote code execution? The output is proven exploitability with documented evidence, not a list of theoretical risks.
Pricing Comparison
Traditional penetration testing typically costs £2,000 to £15,000 per engagement depending on scope, with additional costs for expedited scheduling and retesting. Most organisations can afford one engagement per year, if that.
Revelion pricing by tier:
- Free: 10,000 credits, no payment required, enough to assess a typical web application
- Top-up: from £10 pay-as-you-go, no monthly commitment
- Pro - £99/month: 100,000 credits, 25% bonus on top-ups, 5 scheduled scans
- MSP - £299/month: 300,000 credits, 33% bonus on top-ups, 50 scheduled scans, 25 client workspaces, white-label
For a startup running quarterly tests at the Pro level, the annual cost is £1,188. For the same coverage via traditional pentesting at £3,000 per engagement, the annual cost is £12,000.
Why AI Pentesting Can Be Affordable
Traditional pentesting is expensive because skilled pentesters are scarce, billing day rates that reflect both their expertise and the market for that expertise. An engagement requires scheduling around consultant availability, travel for on-site work, and significant manual effort for every step from recon through reporting.
AI agents are not subject to those constraints. Once built, they scale horizontally. The cost of running an AI agent for an additional hour is a fraction of the equivalent consultant cost. That cost reduction passes through to organisations that need security testing, making real pentesting accessible at a price point that makes continuous testing practical.
Affordable does not mean compromised. Revelion runs on the XBOW XBEN benchmark results that rank it above the best-performing human pentesters on standardised vulnerability scenarios. The assessment depth is not reduced to achieve the price point. The delivery model is simply more efficient.
