Advanced Services
Attack Surface Management
Continuously discover, validate, and reduce your external exposure across domains, subdomains, IPs, cloud assets, and third-party services—so you can remediate what attackers can see.
What it is
Continuous visibility into what attackers can see
Attack Surface Management (ASM) is a continuous program that discovers and inventories your internet-facing assets, validates exposures, and helps your team prioritize remediation. It reduces blind spots caused by shadow IT, rapid cloud changes, third-party services, and forgotten legacy systems.
What we monitor (external assets)
- Domains, subdomains, DNS records, and certificate issuance
- Internet-facing IPs, ports, services, and exposed management interfaces
- Web applications, APIs, and authentication entry points
- Cloud-exposed assets (e.g., storage, load balancers, public endpoints)
- Email and brand-related exposures (SPF/DKIM/DMARC posture, lookalike domains)
- Third-party and SaaS exposures where your organization is referenced or integrated
Key deliverables
Actionable outputs your team can use
Attack surface inventory
Maintained list of discovered assets with ownership tags, environment labels, and supporting evidence (DNS, certificates, hosting, and service fingerprints).
Validated exposure findings
Prioritized exposures with severity, business impact, reproduction notes, and remediation guidance—focused on what is exploitable and relevant.
Remediation tracker & verification
Working tracker with owners and target dates, plus re-validation notes to confirm closure and prevent re-introduction of exposures.
Executive summary
Management-ready view of risk trends, top exposures, and progress over time.
Evidence for audit and governance
Documentation that supports security governance and common compliance requirements (asset management, vulnerability management, and change monitoring).
Alerting and escalation notes
Defined alert thresholds and escalation path for high-risk changes (new exposed services, sensitive panels, suspicious DNS/certificate activity).
Engagement approach
A repeatable cycle that reduces exposure
- Confirm scope: primary domains, known IP ranges, cloud tenants, and exclusions.
- Discover & inventory: enumerate assets and tag ownership/criticality.
- Validate exposures: confirm what is real and exploitable to reduce noise.
- Prioritize & remediate: coordinate fixes with clear owners and due dates.
- Verify & monitor: re-check closure and watch for new assets/changes.
Tools / coverage (vendor-neutral)
We use a vendor-neutral approach and can work with your existing stack. Coverage typically includes:
- DNS and certificate transparency monitoring
- Port/service discovery and fingerprinting
- Web exposure checks (misconfigurations, weak TLS, exposed admin panels)
- Cloud exposure checks for public endpoints and risky configurations
- Credential and leak monitoring signals (where applicable)
- Change detection and alerting based on agreed thresholds
Who it’s for
Teams that need continuous external visibility
- Organizations with frequent cloud and web changes
- Companies with multiple brands, domains, or subsidiaries
- IT/security teams managing many internet-facing services
- Compliance-driven organizations that need evidence of continuous monitoring
- Businesses concerned about shadow IT and third-party exposure
Service Overview
What’s included
A practical, repeatable program that identifies your internet-facing assets, validates exposures, and drives measurable reduction in risk over time.
Asset discovery & inventory
Enumerate domains/subdomains, IP ranges, cloud endpoints, and externally reachable services. Identify ownership and tag assets by business unit, environment, and criticality.
Exposure validation & prioritization
Validate findings to reduce noise and focus on exploitable conditions (misconfigurations, exposed admin panels, weak TLS, leaked credentials, risky services, and shadow IT).
Remediation tracking & verification
Track fixes with clear owners and due dates. Re-scan and re-validate to confirm closure and prevent re-introduction of exposures.
Continuous monitoring & alerting
Monitor for new assets and changes (new subdomains, certificate issuance, DNS changes, newly exposed ports/services) and alert your team based on agreed thresholds.
Outputs
Deliverables
Clear, audit-friendly documentation and actionable artifacts your team can use immediately.
Attack surface inventory
A maintained list of discovered assets with tags (owner, environment, criticality) and supporting evidence (DNS, certificates, hosting, and service fingerprints).
Exposure findings & risk register
Prioritized findings with severity, business impact, reproduction steps, and recommended remediation mapped to common control domains.
Remediation tracker
A working tracker of issues, owners, target dates, and status—plus verification notes once remediated.
Executive summary
A concise management view of risk trends, top exposures, and progress over time.
Operations
Reporting cadence
Choose a cadence aligned to your risk appetite and operational capacity.
Weekly (recommended for fast-moving environments)
New assets discovered, critical/high exposures, remediation progress, and items requiring escalation.
Bi-weekly
Validated exposure updates, trend snapshots, and verification of closed items.
Monthly (executive-ready)
Risk trend report, top recurring root causes, and prioritized roadmap for the next cycle.
Ad-hoc alerts
Immediate notification for high-risk changes (new exposed services, sensitive panels, credential leaks, or suspicious DNS/certificate activity).
