Detect security vulnerabilities before anyone does by cloud-based web scanner.

Cyber attacks are increasing and are projected to cost $6 trillion by 2025 to the business globally. The good thing is you can manage this risk by using the right infrastructure, tools & skills.

Thousands of online businesses get attacked every day, and some of the largest hacks/attacks happened in the past.

  • Dyn DDoS attack – caused many websites to go down, including Netflix, SoundCloud, Spotify, Twitter, PayPal, Reddit, etc.
  • Dropbox hack– millions of user accounts were compromised
  • Yahoo – data breach
  • Ransomware – many ransomware attacks

A report by Synopsys reveals that 97% of tested applications had vulnerabilities, and 36% had at least one critical or high vulnerability.
