What is Attack Surface Management?
Attack surface management is the practice of continuously discovering and tracking the systems you expose to the internet — domains, hosts, cloud assets, and certificates. It answers "what do we own that is reachable?" It does not by itself answer "how would an attacker socially engineer our people?"
How a Attack Surface Management Attack Works
Discover assets
Scans and cloud connectors inventory external hosts and apps.
Attribute ownership
Assets are mapped to teams and environments.
Assess exposure
Open ports, expired certs, and known vulns are flagged.
Remediate and monitor
Teams close gaps and watch for new shadow IT.
Real-World Example
A company with mature ASM still suffered BEC because scanners never evaluated how much executive travel and vendor detail was public. The missing piece was human OSINT, not another host discovery.
How AiVERSARY Detects Attack Surface Management Risk
AiVersary complements ASM: use ASM for continuous asset inventory; use AiVersary for people-centric OSINT and attack narratives leadership can act on. See also our comparison pages under /compare.

OSINT Reconnaissance
OSINT reconnaissance — Open Source Intelligence gathering — is the first phase of nearly every targeted cyberattack. It's the process of collecting publicly available information about an organization and its people to plan an attack. Everything from your company website and LinkedIn profiles to job postings, DNS records, and conference presentations becomes intelligence. This is exactly the same process AiVersary uses, but we do it first so you can fix what's exposed.
Lookalike Domains
Lookalike domains are registered names that visually or typographically resemble a trusted brand — rn instead of m, extra letters, or alternate TLDs. They power phishing sites, fraudulent invoices, and executive impersonation that bypass casual visual checks.
DNS Hijacking
DNS hijacking redirects users who type your real domain to attacker infrastructure by altering DNS records or registrar control. Victims see the correct hostname in the browser while landing on a fake site — a powerful path for mass credential theft.
Tenant Compromise
Tenant compromise is when an attacker gains administrative control over your organization's cloud environment — your Microsoft 365 tenant, Google Workspace, or AWS account. Unlike stealing a single employee's password, this gives the attacker the keys to everything: every email, every file, every application, and every user account in your cloud infrastructure. It is the most devastating outcome of a successful credential attack.
