Waratek is the Security-as-Code platform that enables security teams to automate the management of security behavior to reduce human error, remove false positives, and maintain lockstep with the rapid rate of code changes and deployments. Never before have security teams solved security at scale by protecting every application in their enterprise or patching vulnerabilities at scale with modern application development without a single code change, assistance from engineering, or fear of regressions in future releases. Business Description: The world’s largest companies trust Waratek products to scale Security with modern software development. Waratek, the Security-as-Code pioneer, empowers immutable control through policy that eliminates toil spent on false positives and automates the remediation of code vulnerabilities. Deploy software updates without the risk of vulnerability regression and no longer choose between being competitive and being protected. Products and Services: Web applications are the most significant attack vector. Other Security platforms act as large data pipelines that ingest, transform and analyze network traffic resulting in alerts fatigue, where 75% of companies spend more time on false positives than on actual attacks. Waratek addresses these deficiencies and embeds Security inseparably in your applications. Value Proposition Security teams can not keep up with rapid code changes; in fact, 79% of companies knowingly deploy vulnerable code. Companies should not have to choose between being competitive and being protected. Waratek’s Security-as-Code platform automates vulnerability detection, and remediation with immutable and continuous security applied to every deployment
