The containment layer your stack is missing

Traditional controls try to block every possible infection path. BullWall adds a last line of defense at the file layer, detecting illicit encryption the moment it starts and triggering automated isolation within seconds. No signatures, no endpoint agents, no performance drag.

  • •Agentless deployment, nothing to install on endpoints.
  • •Detects live encryption and exfiltration, stopping spread in seconds.
  • •24x7 automated response with built-in isolation actions.
  • •Protects SAN, NAS, application and database servers, on-prem and cloud shares.
  • •Lightweight, with no constant user or admin babysitting required.
  • •Evidence and reporting for governance and compliance.
Ransomware containment architecture

BullWall complements EDR, XDR, SIEM, NAC and perimeter controls as a last line of defense at the file level.

How it works

1) Monitor & Detect

Real-time monitoring across file shares, domain controllers, application and database servers. Multiple sensors, including ML-based signals, identify illegitimate encryption and data theft activity.

2) Isolate & Quarantine

Automatically isolate compromised users and devices within seconds to prevent lateral spread. Execute remedial scripts and alert IT teams via dashboard, email, SMS or integrated tools.

3) Recover & Report

Identify impacted files for restore from backups and generate audit-ready incident reports with full attack footprint and timeline.

Scale & Integrations: Works alongside your existing stack via REST APIs and common platforms such as SIEM, EDR and NAC. Suitable for SMB to global enterprise.

Managed Security Approach

  • •Secure network architecture
  • •Continuous monitoring & updates
  • •Policy optimisation
  • •Integration with connectivity and VoIP infrastructure

Modern ransomware can encrypt tens of thousands of files per minute per infected machine. A file-level containment layer is essential to stop it quickly and protect your business.
