* Obtaining extended information about the IP address allows you to determine the geographical location based on the IP address, check the presence of the address in the lists of proxy servers: Tor, VPN, Mobile or hosting sites, etc. The functionality is included in the software price and does not require the connection of third-party databases.

🔗 Nemesida® AI – a machine learning module

Accuracy of identification of the attacks Nemesida AI is about 53.04%* more efficient than signature analysis.
Machine learning method The Nemesida WAF operation is based on classical machine learning algorithm «Random Forest», that is able to detect attack with minimum response time, nearly without false positives.
Hardware resource requirements Unlike training models using neural networks, classical machine learning algorithms do not require much processing power, so the processor of the Intel Core i3 family or higher will be sufficient for calculations.
Additional features
  • Adaptation of WAF to a mutable application
  • Automatic creation of behavioral models
  • Detection of anomalies and assessment of their severity level
  • Identification of new signs of attacks, including the identification of «zero day» attacks
  • Behavioral models management interface (additional training of models)
  • Ability to change the training period of behavioral models
  • Additional training of models using a backup copy of the training sample

* Test result of Nemesida WAF using only signature analysis and AI/ML (detection accuracy: 46.62% and 99.66%, respectively). The testing was performed using the specialized WAF Bypass Tool. Based on the test results, the use of machine learning improves detection accuracy by 53.04%.

Diagram of Nemesida WAF modules interaction

1 Includes Nginx, the Nemesida WAF dynamic module and the Nemesida AI MLA machine learning agent.

  • Nemesida WAF dynamic module carries out a signature analysis of requests coming to the server and, based on the behavioral models built by Nemesida AI MLC, makes a decision to block them or transfer them to other modules.
  • Nemesida AI MLA machine learning module applies behavioral models built by Nemesida AI MLC to requests received from the dynamic module and sends a blocking command.
  • Nemesida AI MLC machine learning module is designed to build behavioral models and detect other anomalies (for example, Brute-force, Flood, DDoS L7).
  • The Nemesida WAF API is designed to receive information about attacks and identified vulnerabilities, as well as transmit information about blocked requests and the results of the Nemesida AI and Nemesida WAF Scanner modules to the PostgreSQL DBMS.
  • Nemesida WAF Cabinet is designed for visualization and analysis of the events of the components from the PostgreSQL DBMS, management of Nemesida WAF settings, management of OpenAPI query schemes, configuration of the use of behavioral models built and applied by the Nemesida AI module, as well as systematization of information about anomalies and identified vulnerabilities.
  • The Nemesida WAF Scanner Vulnerability Scanner is designed to detect vulnerabilities in a protected web application.
Additional Information
  • Blocking an individual request
  • Temporarily blocking requests from the source by IP address
  • No artificial restrictions on traffic, RPS and the number of virtual hosts
  • Validate HTTP Transactions for RFC Compliance and Best Practices
  • Categorization by the type of activity (type of attack) of sources
  • Detection of bots based on their traits and behavioral analysis
  • Creation of signatures and their exclusions based on a set of criteria (for example: method, URL, parameter value, headers) and regular expressions
  • Using machine learning to minimize false positives and detect unknown attacks, easy management of the learning or retraining process via a web interface
  • Support for WebSockets, XML, JSON
  • Integration with ClamAV antivirus, SIEM systems and firewalls
  • Analysis of web application vulnerabilities using Nemesida WAF Scanner
  • Noncommercial version with limited functionality Nemesida WAF Community Edition with basic protection of web applications from OWASP attacks based on signature analysis
  • Access to the GeoIP service, which does not require the connection of additional files, modules, etc.

Filtering and notifications
