PICUS: Breach & Attack Simulation (BAS)
Primary Guard deploys PICUS BAS to move enterprises from assumed security to proven security. Our certified specialists run continuous, safe attack simulations and translate the results into vendor-specific detection rules for your SIEM, EDR and NDR.
Proven security, not assumed security
Primary Guard delivers Picus Security Malaysia deployments as a managed breach attack simulation Malaysia service. Our BAS Malaysia practice continuously simulates real-world adversary techniques against your live environment so you know exactly what is detected, blocked, or missed — mapped to MITRE ATT&CK and tuned into your SIEM, EDR and NDR rules.
Beyond Annual Pentests
Most enterprises only discover their security gaps after a breach. Annual pentests are a snapshot — they go stale within weeks of the next config change or rule update. Without continuous validation, your SIEM, EDR and firewall rules slowly drift out of effectiveness while compliance reports keep saying you are 'protected.'
Proven, Not Assumed
PICUS safely runs thousands of real attack techniques against your live environment, then tells you exactly which controls failed and how to fix them — with vendor-specific mitigation content. You see your true MITRE ATT&CK coverage in a live heatmap, not in vendor marketing claims.
What PICUS Validates Continuously
Multi-layered validation across every control in your stack. Primary Guard's breach attack simulation service continuously tests your firewalls, endpoints, email gateways, and SIEM detection rules against real-world attack scenarios — giving you a clear, evidence-based picture of where your defences hold and where they need improvement.
Network & Perimeter
Simulates exploits, lateral movement and data exfiltration to validate your firewalls, IPS and NDR rules — surfacing gaps before attackers do.
Endpoint & EDR
Executes real malware behaviours and adversary techniques in a contained way to confirm your EDR is actually detecting and blocking — not just reporting.
Email & Web Gateway
Tests phishing, malicious attachments and URL-based payloads against your email and web filtering controls so social-engineering paths stay closed.
Frequently Asked Questions
Detection Gap Closed
Customers running PICUS continuously close on average 70% of their detection gaps within the first 90 days — with vendor-specific mitigation content for Splunk, Sentinel, CrowdStrike and more.

Annual or even quarterly penetration tests give you a snapshot of your security posture on a single day. The problem is that your environment changes every day — new endpoints, firewall rule updates, cloud workload deployments, identity policy changes and signature updates from your EDR vendor all silently shift what is actually being detected and blocked.
By the time the pen test report is delivered six weeks later, half the findings are stale and the controls you assumed were working may have already drifted. Threat actors do not wait for your next scheduled assessment — they continuously probe, and so should your defences. Continuous Breach & Attack Simulation closes that gap by safely emulating real adversary techniques against production controls, every day, without disrupting users.
What Primary Guard Delivers
Primary Guard delivers Picus Security as a fully managed Breach & Attack Simulation service from Malaysia. Our analysts deploy Picus agents across endpoints, network segments and email gateways, then continuously execute the latest adversary techniques mapped to the MITRE ATT&CK framework — including ransomware, lateral movement, credential theft and data exfiltration scenarios.
Every gap is prioritised by exploitability and business impact, with vendor-specific mitigation guidance for the controls you already own — Cloudflare WAF, Stellar Cyber XDR, Microsoft Defender, Fortinet, Palo Alto and more. Clients typically close 70 percent of exploitable gaps within the first 90 days, measurably reducing their attack surface without buying additional tooling.
Common use cases include validating EDR and SIEM detection coverage, proving control efficacy to auditors for RMiT and ISO 27001, benchmarking before and after major infrastructure changes, and generating board-ready security posture metrics that go beyond vulnerability counts.
