Assessment<\/p>\n<\/div>

Secure Before You Deploy | SSAT Services<\/h1><\/div>

Firmus provides System Security Acceptance Testing (SSAT) services to validate that systems, applications, infrastructure, and security controls are securely implemented and meet the organization\u2019s cybersecurity, compliance, and operational security requirements prior to production deployment or project acceptance.<\/p>\n

Our SSAT approach focuses on <\/span>identifying security weaknesses, configuration issues, integration risks, and operational gaps before systems are fully commissioned into live environments. The assessment helps organizations reduce deployment risk, improve security assurance, and validate that implemented controls function as intended.<\/p>\n<\/div><\/div><\/div>
