Find the gaps before attackers do.
Is your website, network or cloud infrastructure vulnerable to a cyber attack? Xanthus Security's certified testers think like adversaries so you can fix what matters first.
Two ways to see your organization through an attacker's eyes.
From a focused test of a single application to a full-scope adversary simulation, our engagements are scoped to your environment and delivered by people who do this every day.
Penetration testing
Web, network, cloud, Wi-Fi, ICS, IoT or any other kind of penetration test. Our team holds current certifications such as OSCP, GPEN, GWAPT, GMOB and CRTL, and has the depth to meet your requirements.
Every finding is confirmed by hand and exploited where it's safe to do so. You get a clear report that shows what an attacker could actually do, ranked so your team knows what to fix first. Available as a one-off test or as an ongoing service.

Red teaming
In-depth engagements that show the weaknesses in your enterprise from an outsider's perspective. Open-source intelligence, phishing, physical security and internet-facing attacks are just a few of the techniques we use.
Where a penetration test asks what's vulnerable, a red team asks whether a determined attacker could reach what matters most, and whether your team would notice. We measure your detection and response as much as your defences.

- Detection & response
