Know your attack surface
before attackers do
Offensive360 ASM continuously discovers and monitors everything your organization exposes to the internet — domains, subdomains, hosts, open ports, services, certificates, and leaked credentials. From a seed scope it enumerates your external surface, scores each exposure by risk, and watches for change on an hourly or daily cadence, so a forgotten staging host or an expiring certificate never becomes an attacker's way in. And because it is part of one platform, every asset it finds feeds straight into the DAST engine and AI Pentester for authorized validation — on-premise or fully air-gapped via the Offensive360 OVA.

What Offensive360 ASM does
Continuous external discovery and monitoring — every asset you expose, every exposure on it, ranked by the risk it carries.
Continuous Asset Discovery
From a seed scope, the engine finds the domains, subdomains, and hosts your organization exposes — continuously, not once — and keeps a de-duplicated, organization-scoped inventory.
Subdomain Enumeration
Passive sources plus active brute-forcing surface the subdomains attackers would find, including forgotten staging, admin, and legacy hosts that never made it onto an asset list.
Ports, Services & TLS Posture
Resolved hosts are checked for open ports, running services, and SSL/TLS certificate posture — the exposed services and weak or expiring certificates that widen your surface.
Breached-Credential Monitoring
OSINT breach sources are correlated against the domains and emails in scope, surfacing leaked and breached credentials tied to your organization so you can force resets fast.
Risk Scoring & Prioritization
Every exposure is scored and rolled up into an organization risk view, so your team works the highest-risk assets first instead of drowning in a flat inventory.
Scheduled Monitors & Alerts
Define monitors over a scope of domains and alert emails at an hourly or daily cadence; when the surface changes — a new host, port, service, or breach — the change is recorded and can alert you.
How discovery runs
Five continuous steps — from a seed scope to an always-current, risk-ranked view of your external surface.
Seed the scope
Point ASM at the domains (and emails) you own. A full URL, a bare domain, or a list all work — the engine normalizes them to the hosts it should watch.
Discover assets
Subdomain enumeration, host resolution, and port and service discovery build a live, de-duplicated inventory of everything you expose — organization-scoped and safe against production.
Detect exposures
Exposed services, TLS/SSL posture, misconfigurations, and OSINT breach signals — including leaked credentials — are attached to each asset as findings.
Score & prioritize
Each exposure is risk-scored and rolled up into an organization risk view, so the surface is ranked by what an attacker would reach first.
Monitor continuously
Monitors re-run discovery on an hourly or daily cadence and alert on change — and the assets they find feed straight into DAST and the AI Pentester for authorized validation.
An attack surface you can act on — not just a list
Most attack surface tools stop at an inventory in someone else's cloud. Offensive360 ASM is part of one unified, on-premise-capable platform: it discovers continuously, scores every exposure by risk, and hands the assets it finds straight to the DAST engine and the AI Pentester for authorized validation — so discovery turns into fixes, not just a longer list.
One platform, not a bolt-on
The assets and exposures ASM discovers feed directly into the Offensive360 DAST engine and AI Pentester — discovery, validation, and reporting in one appliance.
Safe against production
Discovery is bounded to the scope you authorize and runs behind an egress control; it inventories and monitors, it does not exploit or disrupt what it finds.
Continuous, not a snapshot
Scheduled monitors re-run discovery on an hourly or daily cadence, so a newly exposed host or an expiring certificate is caught while it still matters.
Risk-scored and prioritized
Exposures are scored and rolled up into an organization risk view, so your team always knows the highest-risk asset to work next.
On-premise & air-gapped
Runs via the Offensive360 OVA on-premise or air-gapped — your asset inventory and exposure records never leave your network.
What a monitor watches
Each monitor runs discovery over a scope on a schedule and records what changed — for example:
- New subdomains and hosts appearing on your surface
- Newly opened ports and exposed services
- Weak, misconfigured, or expiring TLS/SSL certificates
- Leaked or breached credentials for your domains and emails
- Exposures ranked by an organization risk score
Monitors run hourly or daily, are scoped to your organization, and can alert the emails you choose the moment your surface changes.
Built into the Offensive360 platform
ASM feeds the same engine as Offensive360 DAST and the Autonomous Red Teaming engine — the assets it discovers become the scope you validate. Pair it with SAST and MAST for full-stack coverage, all inside one on-premise or air-gapped appliance.
Attack Surface Management FAQ
How continuous attack surface management works in 2026.
What is Attack Surface Management (ASM)?
Attack Surface Management is the continuous discovery, inventory, and monitoring of everything your organization exposes to the internet — domains, subdomains, hosts, open ports, services, certificates, and leaked credentials — so you find and fix exposures before an attacker reaches them. Offensive360 ASM runs this discovery continuously from a seed scope, scores each exposure by risk, and alerts you when your external surface changes.
How does Offensive360 ASM discover assets?
From a seed domain (or a list of domains and emails), the engine enumerates subdomains through passive sources and active brute-forcing, resolves hosts, discovers open ports and running services, inspects TLS/SSL certificate posture, and correlates OSINT signals such as leaked emails and breached credentials. Every discovered asset is de-duplicated, scoped to your organization, and tagged with the exposures found on it.
Does ASM monitor my attack surface continuously?
Yes. You define one or more monitors over a scope of domains and alert emails, choose an hourly or daily cadence, and the engine re-runs discovery on schedule. When a new asset, port, service, or exposure appears — or a breached credential is found — it is recorded against your organization and can raise an alert, so a newly exposed host or an expiring certificate does not sit unnoticed.
Is Offensive360 ASM safe and non-intrusive?
Yes. Discovery is designed to be safe against production: it is bounded to the scope you authorize, its outbound reconnaissance runs behind an egress control so it cannot wander outside your assets, and it does not exploit or disrupt the services it finds. ASM builds the exposure picture; the Offensive360 DAST engine and AI Pentester handle any authorized, deeper testing.
Can ASM run on-premise or air-gapped?
Yes. Offensive360 ASM deploys via the Offensive360 OVA and runs fully on-premise. In air-gapped networks it discovers and monitors the internal surface you scope, with no requirement to send asset data to a cloud service — asset inventory and exposure records never leave your environment.
Does ASM detect breached and leaked credentials?
Yes. During discovery the engine correlates OSINT breach sources for the domains and emails in scope, surfacing leaked or breached credentials tied to your organization so you can force resets and close the exposure. Breach findings are scored and prioritized alongside the rest of your external surface.
How is Offensive360 ASM different from a standalone ASM vendor?
Standalone ASM products are typically cloud-only and stop at an inventory. Offensive360 ASM is part of one unified platform: the assets and exposures it discovers feed directly into the DAST engine and the AI Pentester for authorized validation, it deploys on-premise and air-gapped, and its risk scoring prioritizes what to test next — discovery, validation, and reporting in one appliance rather than a bolt-on.
See your attack surface the way an attacker does
Continuous discovery and monitoring of every asset you expose — subdomains, ports, services, certificates, and leaked credentials — risk-scored and validated inside one platform. On-premise or air-gapped, so nothing leaves your network.
