# Security

**The Edge Protocol** is built upon the robust **cSigma Institutional** infrastructure, designed to ensure secure and efficient institutional lending. This infrastructure has facilitated a substantial number of loans to institutional borrowers, leveraging a proven smart contract framework. 

The cSigma platform has undergone extensive security audits, with numerous reviews conducted by leading firms. Most notably, the **cSigma Edge contracts** have been rigorously audited by **QuillAudits**, ensuring their security and reliability ([view audit report](https://github.com/csigma-labs/audit-reports/blob/main/cSigma%20Edge%20Audit%20Report%20-%20QuillAudits.pdf)). Additionally, the core **cSigma Institutional contracts** have been audited by **ImmuneBytes** ([view audit report](https://github.com/csigma-labs/audit-reports/blob/main/cSigma%20Institutional%20Audit%20Report%20-%20Immunebytes.pdf)), and the **cSigma Token contract** has also been reviewed by **QuillAudits** to uphold the highest standards of security ([view audit report](https://github.com/csigma-labs/audit-reports/blob/main/cSigma%20Token%20Audit%20Report%20-%20QuillAudits.pdf)).
