External Attack Surface Management (EASM) for UK Businesses
You can't defend what you can't see. AMVIA's SurfaceLoop platform continuously discovers and monitors your internet-facing assets — domains, IPs, email authentication records and dark-web exposure — then prioritises the findings that actually matter. Free 14-day trial, audit-ready evidence built in.
External Attack Surface Management (EASM) continuously discovers and monitors everything your business exposes to the internet — domains, subdomains, IPs, email authentication records and leaked credentials on the dark web — so unknown and forgotten assets stop being the way in. AMVIA delivers EASM through SurfaceLoop, our attack surface monitoring platform, with a free 14-day trial and audit-ready evidence export.
Why external attack surface management matters now
Every business accumulates internet-facing assets faster than it retires them: marketing microsites, trial subdomains, cloud services spun up for one project, mail records nobody has reviewed since setup. Attackers enumerate all of it systematically — 43% of UK businesses experienced a breach or attack in the past 12 months, and 85% of breaches involved phishing (DSIT, Cyber Security Breaches Survey 2025), an attack that starts with what's visible and spoofable from outside. EASM turns that outside view into your own operational picture.
The visibility layer in a security-first stack
EASM is deliberately one layer, and it works best wired into the rest: vulnerability management assesses the estate SurfaceLoop discovers, penetration testing proves what's actually exploitable, and AMVIA's managed cybersecurity services act on the findings day to day. SurfaceLoop itself is honest about its boundary — it's discovery, monitoring, dashboards and reports, not a managed SOC — which is exactly why it pairs well with a provider that runs those services too.
What you get from the first 14 days
The free trial runs the full workflow: seed your apex domains, auto-discover the footprint, verify what's yours, then watch continuous scanning prioritise the high-risk findings with CVE intelligence — and export audit-ready evidence when remediation lands. For most businesses the first footprint review is the business case: the assets you'd forgotten are the ones nobody was patching. Start at SurfaceLoop or talk to the team about running EASM as part of a wider managed security engagement.
Why the External View Matters
What SurfaceLoop EASM Covers
Asset Discovery
Start from your apex domains; SurfaceLoop auto-discovers the footprint behind them — subdomains, IPs and services you may not know are exposed, including shadow IT.
Continuous Monitoring
Deep scanning and continuous monitoring of domains, IP addresses and email authentication records — your attack surface is watched between pen tests, not just during them.
CVE Intelligence & Prioritisation
Findings are matched against deep CVE intelligence and prioritised by risk, so your team acts on the exposures that matter rather than wading through noise.
Dark Web & Email Exposure
Dark-web monitoring for business email addresses and phishing-relevant exposure — know when credentials tied to your domains surface where they shouldn't.
How SurfaceLoop Works
Seed your domains
Input your primary apex domains — that's all SurfaceLoop needs to start.
Discover and review the footprint
Auto-discovery maps the assets behind your domains; you verify what's genuinely yours before monitoring begins.
Monitor, prioritise, act
Continuous deep scanning with alerts on high-risk findings, CVE-matched and prioritised — with audit-ready evidence packets when you need to prove remediation.

Frequently Asked Questions
EASM is the continuous discovery and monitoring of everything your organisation exposes to the internet — domains, subdomains, IP addresses, services, email authentication records and credential exposure on the dark web. It answers the question every attacker asks first: what can I see and reach from outside? Unknown and forgotten assets are a common way in, and EASM makes them visible before someone else finds them.
Vulnerability scanning assesses assets you already know about; a penetration test is a point-in-time exercise against an agreed scope. EASM works the other way around — it discovers what's exposed (including assets you didn't know you had) and monitors continuously between tests. The three are complementary: EASM finds the estate, vulnerability management assesses it, and pen testing proves what's exploitable.
SurfaceLoop is AMVIA's attack surface monitoring platform: asset discovery from your seed domains, continuous monitoring of domains, IPs and email authentication records, dark-web monitoring for business email exposure, CVE-matched prioritisation, and audit-ready evidence export. It comes with a free 14-day trial on a business subscription.
No — SurfaceLoop is the visibility layer: discovery, monitoring, dashboards and reports, not a managed SOC or incident response service. That's deliberate and honest. Where findings need acting on, AMVIA's wider managed security services — including 24/7 monitoring on Enterprise plans, vulnerability management and penetration testing — pick up from what SurfaceLoop surfaces.
Discovery starts from nothing more than your apex domains, and the free 14-day trial is designed to show you your real attack surface — including assets and exposures you didn't know about — before you commit to anything. Most businesses find the first review of the discovered footprint is the eye-opener.
