The perimeter has gone. The attack surface hasn't.
Cloud adoption, remote working, SaaS sprawl, and shadow IT have created an attack surface that no traditional asset management tool can fully capture. Acquisitions bring in unknown infrastructure. Development teams spin up cloud resources outside of IT's view. Partners and suppliers extend your exposure beyond your own walls.
Attack Surface Management gives you the attacker's perspective — continuously discovering internet-facing assets, identifying exposures, and flagging what needs attention. Nomios combines specialist tooling with consultancy-led analysis to turn raw discovery data into prioritised, actionable intelligence.
Four dimensions of your attack surface
Your exposure extends well beyond your known infrastructure. We map all of it.
- A continuous, outside-in view of everything your organisation exposes to the internet — seen exactly as an attacker would see it. IP ranges, domains & subdomains Exposed services, ports & protocols SSL/TLS certificate monitoring Misconfigured & vulnerable services
- Cloud environments grow fast and drift faster. We identify exposed cloud assets, misconfigurations, and orphaned resources across AWS, Azure, and GCP. Cloud resource discovery & inventory Public-facing storage & database exposure Misconfigured access policies Unmanaged & orphaned resources
- Business units, developers, and remote teams create assets outside IT's view. We surface what your internal tools miss — before attackers exploit it. Unauthorised cloud accounts & services Unmanaged SaaS applications Forgotten dev & test environments Third-party & supplier exposure
- Your attack surface includes your brand and digital identity. We monitor for typosquatting, impersonation, exposed credentials, and reputational threats. Lookalike domain & typosquat detection Brand impersonation monitoring Exposed credentials & leaked data Social media & web presence risks

Consultancy-led, tooling-supported
We don't just deploy a scanner and send you a dashboard. Our consultants work with you to interpret findings in the context of your business — turning raw discovery data into a clear, prioritised action plan.
STEP 1: Discovery & baseline
- We build a comprehensive, outside-in inventory of your attack surface — including assets you may not know about — using best-in-class discovery tooling.
STEP 2: Analysis & prioritisation
- Our consultants analyse the findings in the context of your business, risk appetite, and threat profile — separating signal from noise and prioritising what matters.
STEP 3: Continuous monitoring
- Your attack surface changes every day. We keep watch continuously — alerting you to new exposures, changed configurations, and emerging risks as they appear.
Services that fit your team
From a one-off discovery engagement to a fully managed continuous programme.
Professional services
Tool deployment, integration with your CMDB and ticketing workflows, and knowledge transfer — so your team can operate with full visibility from day one.
Managed services
Continuous monitoring, expert triage, and regular reporting — delivered as a fully managed service so your team stays focused on remediation, not discovery.
Consulting services
Attack surface assessment, scope definition, and remediation roadmap. We help you understand your exposure baseline and build a plan to reduce it systematically.
What sets us apart
Consultants, not just a platform
- Any tool can generate a list of assets. Our consultants provide the context, analysis, and prioritisation that turns discovery data into decisions.
Connected to your vulnerability programme
- ASM findings feed directly into your vulnerability management and penetration testing workflows — closing the loop between discovery and remediation.
Outside-in, not inside-out
- We look at your organisation the way an attacker does — from the outside. Not just what your internal tools report, but what the internet actually sees.
Continuous, not periodic
- Your attack surface changes daily. We monitor it continuously — not just during an annual assessment — so new exposures are caught before they are exploited.
How large is your attack surface, really?
The answer usually surprises organisations. Start with a discovery engagement and find out what the internet sees when it looks at you.
