You need state-of-the-art authentication for your web application. You need APIs to integrate with your application's signup process. You need someone to watch your user accounts for suspicious activity or hacking attempts and to take steps to notify and protect them immediately. You need to know when user passwords have been compromised and automatically notify them to change their passwords. You need these things to be part of a larger workflow so you can automate your business and reduce costs. You need all this on a budget because hiring senior developers, cybersecurity experts, and security operations staff is too expensive. You can have it all.

Is your site vulnerable to proxy phishing attacks?
Cryptium Logo

Web applications that use standard 2FA techniques remain vulnerable to proxy phishing attacks. This is when an attacker uses an email or web link to trick users into browsing at the attacker's web server instead of your own, and the attacker's website is made to look and work exactly like your own website.

When users enter their username, password, and 2FA code into their browser it is actually sent to the attacker's website and the attacker can take control of their accounts. The attacker can then show them a bogus error message that the system is down and for them to return later, or even show them a tampered view of your website after they sign in.

Xentri uses a patented anti-phishing system that protects users against regular phishing and also against sophisticated proxy phishing attacks.
