Cybercrime is spreading at an alarming rate and has become a global multi-billion-dollar criminal operation. Every day cyber criminals develop new and more advanced means for online attacks. They employ malicious software such as Trojans and continually seek to disrupt critical online transactions. While banks and their customers are most often the target, malicious attacks have spread to the online gaming and gambling industries as well as many public institutions. In fact, all organizations using internet for the communication of sensitive information are prey to the ever-growing threat.


The call for a new security paradigm

Cybercrime and cyber spying cost the US economy enormous amounts of money. Online banking alone loses an estimated 3-4 billion dollars per year as a result of hacker attacks. A new security paradigm is needed in the fight against cybercrime. Enterprises and organizations can no longer afford to remain one or more steps behind hackers.


Unfortunately in the war on cybercrime, end users often compound the challenge. Many customers are unwilling to take security measures such as installing or downloading a security application when interacting with a website. In the case of online banking, customers often feel they have nothing to gain from securing their online session, as any potential loss in many countries will be covered by the bank.


Securing you and your customer’s online session

CodeSealer enables banks and companies to add a secure layer of protection for online sessions without the end-user needing to take action. In fact, the customer does not even know CodeSealer security software is running. Banks and organizations no longer need to rely on their customer to secure his own device, CodeSealer does it for them.


CodeSealer is the only IT security company to enable secure sessions without any end-user effort required. In a market where customer loyalty means everything, CodeSealer creates a very important competitive parameter for your organization.

THE story


In 2006, CodeSealer founder, Martin Boesgaard, began developing a unique security technology initially designed to protect online banking against cyber threats. His ground-breaking technology developed into the CodeSealer Web Session Firewall - our patented solution that protects web sessions and online transactions from malicious software and attacks.


Boesgaard’s solution was clearly ahead of its time. As threat scenarios became more sophisticated and cybercrime increased dramatically, CodeSealer attracted venture capital that since has been applied to accelerate the development of the technology and the company.


From its launch, CodeSealer has focused primarily on the online banking sector. The banking industry has a great need for security. Banks must be in total control of web security and cannot be dependent on an end-user’s device security.


CodeSealer’s core technology provides:

• secure sessions regardless of the security level of the accessing device

• a solution which does not require any action from the end-user

• a solution completely invisible to the end-users

• compatibility with all browsers

• security on any device


As eCommerce continues to grow, other industries now take advantage of our Web Session Firewall solutions. In fact, any organization that depends on a secure communication with end-users via a browser will benefit from the Web Session Firewall.


When a password is required on a website, there is information worth protecting. CodeSealer Web Session Firewall provides an always-secure session.
