TAC Security announced that it has added leading AI and technology companies as clients for its ESOF AppSec Application Security Assessment. The new clients, onboarded in April, include Anthropic, Perplexity AI, Replit, Odoo, and Litera. This development highlights the reliance of advanced technology firms on independent, third-party application security validation despite the rise of AI-powered security capabilities.
