Attack Surface Management
Discover every asset attackers can see. Monitor them continuously. Eliminate exposure before it becomes a breach.
Core ASM capabilities
Automated asset discovery
Xentinel crawls DNS records, certificate transparency logs, port scans, and web archives to find every subdomain, IP, and service associated with your organization — including assets your team forgot about.
Continuous monitoring
Unlike one-time pen tests, Xentinel monitors your attack surface around the clock. New assets are detected and assessed within minutes of exposure.
Change detection and alerting
When a new port opens, a service changes, or a new domain resolves to your infrastructure, Xentinel alerts you immediately via email, WhatsApp, or Slack.
Vulnerability validation
Every discovered asset is actively probed for known vulnerabilities, misconfigurations, exposed admin panels, default credentials, and OWASP Top 10 issues.
Cloud asset tracking
Xentinel connects to AWS, Azure, and GCP to discover cloud-hosted assets and flag newly exposed services, public storage buckets, and misconfigured security groups.
Frequently asked questions
What is Attack Surface Management (ASM)?
Attack Surface Management is the continuous process of discovering, inventorying, and monitoring all external-facing digital assets an organization owns or operates. The goal is to identify and reduce exposure before attackers can exploit it. ASM is distinct from traditional vulnerability scanning because it begins with discovery — finding assets you may not know exist — before assessing their security posture.
What types of assets does Xentinel ASM discover?
Xentinel discovers domains and subdomains, IP addresses and ranges, web applications, APIs (REST and GraphQL), cloud services (AWS, Azure, GCP), exposed storage buckets, SSL/TLS certificates, open ports and services, and shadow IT — cloud resources spun up by teams without central IT awareness.
How is continuous ASM different from a penetration test?
A penetration test is a point-in-time assessment — it tells you about your security posture on a specific day. Your attack surface changes every day as new services are deployed, certificates expire, and cloud configurations drift. Continuous ASM provides persistent visibility, catching changes and new exposures as they happen rather than months later during the next scheduled test.
Does Xentinel require agents or internal network access?
No. Xentinel is fully external and agentless. It operates from the internet, scanning your digital footprint exactly as an attacker would — with no installation, no VPN, and no access to your internal network required.
