Industry security context

Modern SaaS platforms create continuously changing attack surfaces.

SaaS security testing has to keep pace with product releases, integrations, tenant models, and identity changes. A static assessment can miss the paths attackers use when APIs, permissions, cloud services, and administrative functions interact. Tessen Security focuses on realistic SaaS application security scenarios: account takeover, authorization bypass, tenant boundary issues, exposed management workflows, and exploitable misconfigurations that create practical business risk.
