What does the internet already know about you?
Attack surface management discovers and assesses every internet-facing asset linked to your organisation — including the shadow and forgotten ones attackers find first. Start with a free ASM scan.
Attack surface management from Passeca, on the Rapid7 platform, continuously discovers, assesses and monitors every internet-facing asset linked to your organisation — exposed services, forgotten subdomains, shadow cloud accounts and misconfigurations — and prioritises the ones an attacker would actually exploit. Start with a free ASM scan.
What is attack surface management?
Your attack surface is everything an attacker can see and reach from outside. ASM is how you see it before they do.
Your attack surface is the sum of every internet-facing asset linked to your organisation — public cloud services, exposed ports and services, web applications, APIs, DNS records, and the certificates and credentials attached to them. It grows every time someone deploys a new service or lets an old one lapse.
Attack surface management is the continuous process of discovering that surface, assessing it for risk, and monitoring it for change — from the attacker's perspective, not from an internal asset register that is almost always incomplete.
Who needs attack surface management?
- You have cloud and web exposure that changes faster than anyone tracks.
- You have grown by acquisition and inherited assets no one fully mapped.
- You must evidence external monitoring for compliance or customer assurance.
- You have been surprised before by a forgotten subdomain or exposed service.
What the service covers
From discovery to remediation
- 01
Discover
Rapid7 discovers every internet-facing asset linked to your organisation — the ones you know about and, critically, the shadow and forgotten assets attackers find first: exposed services, expired domains, unmanaged cloud accounts.
- 02
Assess
Each asset is assessed for risk — open ports, vulnerable services, misconfigurations and exposed credentials — and prioritised so you fix what an attacker would actually exploit, not every minor finding.
- 03
Monitor
Your attack surface is monitored continuously for change: a new exposed service, a misconfigured cloud bucket, a forgotten subdomain. You learn about new exposure as it appears, not at the next quarterly scan.
- 04
Remediate
Passeca supports or executes remediation — closing exposures, decommissioning dead assets, and tightening configuration — and tracks each finding through to closure.
Powered by Rapid7
Rapid7 provides continuous external attack-surface discovery and assessment, operated by Passeca as part of our partner stack.
Rapid7 discovers and assesses external assets continuously, prioritising exposures by exploitability and business context. Passeca configures, tunes and operates the platform, and supports or executes remediation. Findings feed PassIRP so external exposure becomes part of your overall detection and response picture. See the Rapid7 partner page.
ASM vs vulnerability management
| Attack surface management | Vulnerability management | |
|---|---|---|
| Starting point | What are my assets? | Patch known assets |
| Perspective | External / attacker | Internal / known estate |
| Finds shadow IT | If inventoried | |
| Cadence | Continuous | Scan cycles |
ASM and vulnerability management answer different questions. ASM finds the assets you forgot you had; vulnerability management patches the ones you know about. For the next layer up — prioritising the exposures that are reachable and exploitable across IT, cloud and OT — see our exposure management service.
How long and how much?
The free ASM scan returns an initial view of your external footprint quickly. A full managed service is continuous by design. Pricing reflects the size and complexity of your external estate.
Which compliance requirements this supports
- ISO 27001 — asset identification and vulnerability management controls.
- NIS2 / DORA — proactive risk identification and continuous monitoring expectations.
- PCI DSS — external scanning and scope management for cardholder-data environments.
