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.


Protect you and your end-users.

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 fundamentally untrusted devices.

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

Codesealer, securing the user, 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 daily.
