Our mission


The cybercriminal world cruelly deprives the Internet users from confidential information. Computer users are being plundered without any notice of their virtual identities. Various data is stolen by malicious software or phishing with the use of social engineering techniques. We monitor possible threats on the Internet and we provide our clients with our acquired knowledge in the form of complementary services.


Criminals permanently improve techniques to takeover more devices and steal confidential information. The Internet allows carrying out attacks on a global scale. The network also provides criminals with the ability to instant communication from any place in the world. We consistently reinforce factual knowledge of our team while enhancing used technology for better protection.


An infected device (laptop, server, smartphone) is a huge threat to its user. It is also a threat to all online systems used by all users of this device. The successful attack of hackers can be associated with not only confidential data loss but also loss of funds. Each incident defined as a potential source of danger is analyzed and archived. This allows the PREBYTES SIRT to predict subsequent dangerous space on the Internet and prepare an emergency back-up plan.


24 / 7 Incident readiness and responsiveness

Incidents are handled within 60 minutes after they have been reported. Preliminary analysis is forwarded as an Emergency Response report.
