Attack Surface Management (ASM)

Attack surface management (ASM) gives you an attacker’s view of everything your organisation exposes to the internet. Forgotten subdomains, test servers, misconfigured cloud storage and leaked credentials are among the most common starting points for real breaches. We find them, validate the risk and help you shut them down.

What We Cover

• Asset discovery: domains, subdomains, IP ranges and cloud-hosted services.
• Exposed services: open ports, admin panels, remote access and outdated software.
• Cloud exposure: public storage buckets, exposed databases and misconfigured services.
• Leaked secrets and credentials in public code repositories and paste sites.
• Subdomain takeover and dangling DNS records.
• Shadow IT: assets your security team did not know existed.

Our Approach

We use the same reconnaissance techniques that security researchers and attackers rely on, combining automated discovery with manual validation so you only receive real, prioritised issues. ASM can be delivered as a one-time assessment or as a recurring service with regular reporting of new and changed assets.

What You Get

• A complete inventory of discovered internet-facing assets.
• Validated, risk-rated exposures with remediation steps.
• Trend reporting for recurring engagements.
• Recommendations to reduce and control your attack surface.

• Bug bounty-grade reconnaissance skills applied to your organisation.
• Manual validation so your team is not flooded with noise.

Frequently Asked Questions

How is ASM different from a penetration test?

A penetration test deeply tests a defined scope. ASM continuously finds what should be in scope, including assets you may not know about, and checks them for exposure.

Do you need a list of our assets?

No. Starting from your company name and primary domains, we discover assets the way an attacker would. A known asset list helps us flag unknown ones.

How often is ASM performed?

It can be a one-time assessment, but most organisations benefit from monthly or quarterly monitoring because their attack surface changes constantly.
