Arcseer Watch - Continuous Attack Surface Monitoring

Your last penetration test is already out of date. Systems change constantly - new features ship, dependencies update, infrastructure shifts. A test from six months ago describes a system that no longer exists. That gap is where exposure grows undetected.

Arcseer Watch closes that gap with continuous, real-time monitoring of your attack surface - so you know the moment your exposure changes, not months later.

Most enterprise security programmes test once or twice a year. Between those assessments, your environment evolves daily:

• New endpoints appear every time you deploy
• Dependencies update and introduce unknown risk
• Configuration drift quietly changes your security posture
• New CVEs are published daily against the technologies in your stack

Every one of these changes can create an exploitable entry point your last test never saw. Without continuous visibility, you are operating on outdated assurance.

Real-Time Attack Surface Monitoring Arcseer Watch monitors your technology stack continuously, detecting changes across your environment as they happen - not on a schedule. It identifies new endpoints, configuration changes, and shifts in your infrastructure that could alter your risk profile.

CVE Detection Against Your Stack When new vulnerabilities are published against the specific technologies your environment runs on, Arcseer Watch detects them immediately. You get alerted to relevant CVEs as they emerge, so your team can assess and respond before adversaries take advantage.

Intelligent Alerting When Exposure Changes Not every change warrants action. Arcseer Watch evaluates detected changes in context and alerts you when something materially impacts your exposure. This means fewer false alarms and faster response to genuine risk.

• Continuous monitoring - not scheduled alerts
• Detection of new endpoints and configuration changes in real time
• Newly published CVEs mapped to your specific technology stack
• Alerts triggered by meaningful exposure changes, not noise

Small Security Teams You have limited headcount covering an estate that keeps growing. Arcseer Watch gives you enterprise-grade continuous monitoring without scaling your team - maintaining visibility across your full attack surface so you can focus on remediation and strategy.

Fast-Moving Product Teams You ship multiple times a week. Arcseer Watch aligns to your release cadence, automatically detecting when new deployments or stack changes introduce exposure. Findings integrate into Jira, and retesting needs are identified automatically when significant changes are detected.

Regulated Enterprises You are managing obligations across NIS2, DORA, ISO 27001, PCI-DSS, and more. Arcseer Watch generates compliance-mapped evidence automatically and provides continuous monitoring that satisfies ongoing regulatory requirements through a single dashboard across your full estate.

Arcseer Watch is aligned to industry-recognized standards and frameworks including ISO 27001, OWASP, MITRE ATT&CK, GDPR, and Cyber Essentials+. This alignment ensures that monitoring outputs map directly to the compliance evidence your auditors and regulators expect.

• 72% of organisations attributed direct breach prevention to their penetration testing activity (Bright Defense, 2025)
• 50% faster remediation with hybrid automated and expert review versus point-in-time testing alone (PW Consulting, 2025)
• 41% of security teams cite AI and cloud as their most critical skills gap (ISC2, 2025)

Arcseer Watch is a 12-month continuous monitoring subscription that delivers ongoing, real-time visibility into your attack surface. It is part of the Arcseer AI Offensive Security Platform and works as a standalone continuous monitoring solution or alongside Arcseer Strike for combined penetration testing and monitoring coverage.
