Best Attack Surface Management Platforms in the UK

Most attack surface management tools map infrastructure: domains, hosts, exposed services, unpatched software. Reflectiz covers the layer they do not instrument, the code executing inside the visitor's browser. Every website runs third-party scripts, pixels, trackers, iFrames, and open-source libraries loaded from vendors the organization does not control, frequently pulling in fourth-party code several relationships deep. A site can present a completely clean external attack surface and still be actively skimmed, because the malicious code arrives through a trusted vendor's CDN rather than an exposed port. Reflectiz continuously inventories this web execution surface, baselines the behavior of every component, and alerts the moment behavior deviates. Deployment requires no code changes, no agents, and no access to customer data, typically reaching full coverage within one business day.

We keep you safe by combining AI automated pentesting and elite ethical hacking for both in-depth and in-breadth security testing. It’s not just your code, third-party services, APIs, and external tools all pose a risk to your organization. We give you a complete view of your entire digital exposure so you can understand its weak points. Scanners flag too many false positives and pentests are not frequent enough. Automated pentesting fixes this. It reports less than 0.5% false positives and over 20% of its findings are impactful. We have a pool of world-class ethical hackers ready for human hacking events. To join, they go through an extensive process of background checks and those that get accepted go on to find the most critical vulnerabilities in your assets. Our team has won world-class awards and found vulnerabilities on Shopify, Verizon, Steam, and many more. Add the TXT record to your DNS and start your 30-day free trial.
