About
Alter is an identity security company providing privileged access management (PAM), zero-trust architecture tools, and identity threat detection capabilities for enterprise security teams. As identity-based attacks have become the dominant initial access vector in cyberattacks — credential phishing, MFA bypass, and privilege escalation account for the majority of breaches — protecting and monitoring identity infrastructure has become a top security priority. Alter's platform manages access controls for privileged accounts (admins, service accounts, CI/CD pipelines), detects anomalous identity behavior, and enforces least-privilege access across cloud and hybrid environments.
