Source Code Audits
Thorough code reviews, including line-by-line examination and threat modeling, strengthen project security. They identify vulnerabilities and ensure that best practices in design, dependencies, testing, and documentation are applied
Penetration Testing
Simulating a series of attacks on a system assesses its defense strength and uncovers potential vulnerabilities for attackers to exploit. This leads to recommendations for strengthening security and mitigating potential risks
System Design Review
Examining design specifications, whitepapers, architectural diagrams, and other system documentation ensures security integration into design and architecture. Addressing issues early in the design phase reduces the need for costly changes or potential hacks later in the project's life cycle
