How UpGuard Can Improve Your Cybersecurity
Companies like Intercontinental Exchange, Taylor Fry, The New York Stock Exchange, IAG, First State Super, Akamai, Morningstar, and NASA use UpGuard's security ratings to protect their data, prevent data breaches and assess their security operations.
For the assessment of your information security controls, UpGuard BreachSight can monitor your organization for 70+ security controls providing a simple, easy-to-understand cyber security rating and automatically detect leaked credentials and data exposures in S3 buckets, Rsync servers, GitHub repos, and more.
