Cezurity is a Russian developer of technologies and solutions for protection from a wide range of malware and security threats.

The threat landscape has changed. Today’s cybercriminals are professionals who perform sophisticated attacks of greater diversity than ever before*. Many kinds of malware can “neutralize” or bypass protection designed to handle yesterday’s threats. Ever since it was founded, Cezurity has focused on creating technologies to protect home users and corporate networks in a rapidly evolving environment.

Traditional solutions are no longer able to provide reliable protection. They have fallen behind the surging amount of malware, which can employ low-level attacks and deactivate protection. Heuristic and behavioral analysis, which usually rely on local scans, are of little help here**.

Cezurity’s key technologies include event analysis, monitoring of system changes, and sandboxing of application environments. Most of these technologies are possible thanks to widespread use of cloud technologies and smart Big Data analysis techniques.

Company history


Andrew Woronoff, as specialists in information security, and Alexey Chaley, as data analysis specialist, create a company named Online Solutions.

The mission of the new company is to develop promising technologies for protection against complex threats: sophisticated malware, viruses, rootkits, bootkits, and advanced persistent threats.

Development is started for two key components of proactive defense: the firewall, which monitors network interactions at a very low level (close to hardware) and checks data packets in several places in the network subsystem simultaneously, and Online Solutions Proactive Defense, which ensures the integrity of the software environment and blocks both known and unknown (zero-day) malware.


First version of the Online Solutions Autorun Manager (OSAM) is released. OSAM is a product for monitoring and analyzing modules and programs that are automatically run on system startup (which are the most frequently attacked component of the operating system). The solution performs analysis of all critical autorun areas (file system, system registry, drivers, and services) and scanning for anomalies in these areas. OSAM includes rootkit and malware removal tools.

Utilities are released to assist owners of infected computers with post-infection repair.


Alpha testing is started of Online Solutions Proactive Defense, a proactive protection system that includes such technologies as HIPS (Host Intrusion Prevention System) and anti-rootkit capabilities. A conceptual prototype is developed for protection of 64-bit systems.

A new version of Online Solutions Autorun Manager is released, with improved detection of sophisticated malware.

Development of a cloud-based platform for malware detection is started. The platform is based on evaluation of static and dynamic file properties. Analysis is performed on servers (in the cloud) and offers a substantially different approach from most other anti-virus solutions on the market.


First version is released of the company’s integrated solution for broad-array threat protection: the Online Solutions Security Suite (OSSS). OSSS includes such components as Proactive Defense, Personal Firewall, Autorun Manager, and several other protection technologies developed by the company.


Several major updates are released for all Online Solutions products. Among these is integration of the Online Solutions Security Suite (OSSS) with cloud-based detection technologies.

Cloud-based detection is overhauled, with behavior snapshots of applications now created and analyzed in the cloud.

Online Solutions Security Suite wins second place in the Proactive Security Challenge held by the testing lab Matousec.com.


Natalya Kaspersky, CEO of the Infowatch Group, joins Online Solutions as an investor and strategic partner to get the company’s technologies to market. The company’s name changes to Cezurity.

Development is finished of proprietary Big Data methods for anti-virus analysis.

Cezurity partners with VKontakte, the largest social network in Russia. The agreement includes use of Cezurity technologies to protect users of the social network from malware.


Cezurity’s Anti-Virus Scanner, a cloud-based service for detecting malware and repairing infections, is launched. Anti-Virus Scanner becomes the official tool for VKontakte technical support when helping users to resolve virus incidents.

In the first five months of work, Anti-Virus Scanner is used to scan over 5,000,000 computers and repair thousands of infections.


The company announces the release of Cezurity Cloud, a next-generation cloud-based technology for virus protection. Cezurity Cloud offers the power to resolve a number of tasks for security clients, while maintaining the flexibility for deployment as part of diverse solutions.

Development continues of a proprietary solution for protecting corporate networks from advanced persistent threats (APTs). The solution is based on analysis of anomalies in system changes.

* For example, fewer than 3 million malware samples were in the database of the AV-Test.org laboratory in 2005. This number jumped to over 40 million in 2010 and 100 million in 2012.

** According to 2008 data obtained by Gallup for Eurostat (Eurostat, Confidence in the Information Society, Analytical Report) for users in 27 EU countries, 46% of Internet users had found viruses on their computers in the last five years. 96% of users owned standard security software (firewall and anti-virus/anti-spam software) and 35% employed additional tools for stronger protection.
