Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

The wider availability and use of the Internet bring convenience to the table, but it also welcomes threats of different sorts.

You might have heard about security breaches and losses where businesses and people incur tremendous losses due to Internet vulnerability. Cybercriminals are waiting like hawks to attack whenever they find some weak spots.

Modern-day businesses need to share large files digitally, and in doing so, there always remains a security threat if not done through secure channels. However, not all businesses understand the gravity of the situation as to how fragile the Internet is until they learn it the hard way.

According to statistics, more than 4 billion records were exposed globally due to data breaches in mid-2019. Therefore, regulations such as PCI Data Security Standard and HIPAA guide organizations by providing a framework for storing, handling, and safeguarding their sensitive information.
