Penetration Testing for Technology

Technology companies, from startups to enterprise software providers, face continuous cybersecurity challenges as both targets and custodians of customer data. SaaS providers, cloud platforms, DevOps-driven organisations, and software companies must integrate security testing into their development lifecycles to protect their products and their customers' data.

Penetration testing for technology companies typically covers web applications, APIs, cloud infrastructure, CI/CD pipelines, source code, and the complex microservices architectures common in modern software development. Technology companies often require SOC 2 certification for enterprise customers, making regular pen testing a business requirement.

The rapid pace of development in technology companies means that traditional annual pen testing is often insufficient; many adopt continuous security testing approaches including bug bounty programmes, automated security testing in CI/CD pipelines, and periodic manual pen testing focused on new features and critical components. Penetration testing helps technology companies build customer trust, meet compliance requirements, and ship more secure products.

Technology Pen Testing FAQs

How often should SaaS companies perform pen testing?+

At minimum annually for SOC 2 compliance. Best practice for SaaS companies is quarterly or after major releases, supplemented by continuous security testing in the CI/CD pipeline.

Should we pen test or run a bug bounty programme?+

Both serve different purposes. Pen testing provides structured, comprehensive coverage. Bug bounties provide continuous testing by diverse researchers. Many technology companies use both approaches together.

How do we integrate pen testing into our DevOps process?+

Adopt a 'shift left' approach with SAST/DAST in CI/CD, periodic manual pen testing for deep dives, pre-release security reviews for major features, and annual comprehensive assessments.
