Web Application Cloaking Impossible for Hackers, Invisible for end-users

Our patented technology encrypts and secures web interfaces, cloaking the website code. With codesealing, it’s impossible for hackers to effectively analyze, plan or attack the web application.

A Codesealer-protected web application has:

  • No exposed Code, URL’s or API’s
  • Cloaking makes it impossible to identify vulnerabilities
  • Cloaking also fully protects end-users and prevents tampering with their session
  • Secure application delivery, execution, and communication with end-user

Our technology is high performance, low overhead, and deploys fast, seamless, and versatile into any enterprise infrastructure.

Why Codesealer

Cyber threats

Securing Online Services is extremely challenging, complex and time-consuming

Fraud and cyberattacks are increasing globally with constantly changing attack vectors

Codesealer prevent all of top financial trojans

by preventing vector of attack

The average global cost of cyber crime increased by over 27 percent in 2017.


The average cost per lost or stolen records per individual is $141 — but that cost varies per country. Breaches are most expensive in the United States ($225) and Canada ($190).

Ponemon Institute’s 2017 Cost of Data Breach Study

The financial services industry takes in the highest cost from cyber crime at an average of $18.3m per company surveyed.


Trojan horse virus Ramnit largely affected the financial sector in 2017, accounting for 53 percent of attacks.


Malware and web-based attacks are the two most costly attack types — companies spent an average of US $2.4 million in defense.

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 ensures application resilience, message integrity and privacy between an organization and their end-users. Even when they are compromised

Our Secure content delivery system in JavaScript uses it’s own protocols and encryption engine to deliver, verify, execute and communicate intact JavaScript code on potentially dangerous and untrusted platforms.

Illustration of how CodeSealers Bootload works
  • Our invisible Codesealer Encapsulation Client creates a secure session between application backend 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 (RASP)
  • Your application code is executed as intended and access to your back-end is highly complicated.
