Ready to use, easy to implement solution to protect your client’s web session. Codesealer Cover uses end to end encryption and emulate website in your client browser.

Illustration of how Codesealers WSF workd
  • When deployed at your existing infrastructure all users will be immediately protected.
  • Installed behind the Firewall and the Load Balancer is completely transparent for your web server and your application layer
  • secures HTTP traffic using an additional layer inside the client.
  • Potentially monitors changes to the DOM and prevents illegal modification performed by sources other than Cover .
  • Provides an extra layer of encryption as well as session keys to protect the session.
  • URL’s are encrypted making it significantly more difficult to redirect the user. If the redirect is performed modifying data in the DOM it is protected.
  • Protects, hides and monitor the cookies.
Use case

Financial (Bank & Insurance)

Malware focused on intercepting bank users’ data or redirecting transactions appears very often and evolved very quickly. In addition, bank clients very often do not follow basic security rules and log in from untrusted devices or do not use anti-viruses.

How to keep protected against malware?

Meeting customers and working against the consequences of their mistakes or simply the effects of unfortunate coincidences, which then affect the opinion of a financial institution are the safest solutions. This will prevent unwanted consequences and will have a positive impact on the clients’ trust in the bank.

It is possible to protect key sites from attack vectors, using complex cryptographic systems that are not visible by website users.

Codesealer solution

The Codesealer is securing the user session, makes it impossible to substitute elements of the page, making the malware blind, thus redirecting eg. a bank transfer to the attacker’s account is impossible to do. Attempts of any such attacks are automatically detected and displayed as an alert in the monitoring tool. It is also possible to set different actions in case of detecting malicious activity.

Currently, the Codesealer solution secures over 30 million transactions in the financial sector daily.

Codesealer Enterprise – Secure content delivery system in JavaScript uses its own protocols and encryption engine to deliver, verify and execute intact JavaScript code on potentially dangerous and untrusted platforms. Bootloader can be the core part of other systems.

Illustration of how CodeSealers Bootload works
  • The integrated and dynamic Bootloader in Codesealer Encapsulation Client creates a secure session between Codesealer Server and End-User Client
  • Ensures that the session is encrypted and secured by using unique session keys
  • Performs a specific verification of the runtime environment
  • When the Codesealer Client passes control to the loaded code, we are sure that it has not been modified in any way and that everything is ready for safe launch
