Incident Response

Incident response is a disciplined, rapid approach to managing cyber attacks in real time — minimizing damage, containing the threat, and restoring operations fast. Our mission: get you back in business with minimal disruption and prevent future compromise.

We deploy with a dedicated, field-ready toolkit — including advanced network security devices, servers, and forensics capabilities — enabling immediate containment, secure isolation, and deep on-site or remote analysis without delays.

Attacks can originate internally (accidental or malicious insiders) or externally (phishing, social engineering, advanced persistent threats). 

Our process:

Investigation & Discovery — We immediately deploy specialized hardware and software to uncover breaches, identify attack vectors, and map affected systems.

Containment — Systems are isolated, malicious access points are removed, and malware is eradicated to prevent further spread.

Recovery & Hardening — We restore operations, monitor breach points closely, and implement countermeasures to ensure resilience.

Our services include:

  • Incident management and organization

  • Threat hunting and containment

  • Digital forensics (disk, memory, logs, network)

  • Malware and phishing analysis

  • DDoS analysis and mitigation

  • Executive-level incident communications

  • Customized, actionable reporting

Advanced Persistent Threats (APTs) represent a particularly stealthy and dangerous form of attack. These sophisticated campaigns are often launched by rival organizations or nation-state actors, focused on long-term data theft rather than immediate damage. Once an APT is identified and removed, we continue to monitor for re-entry attempts and reinforce defenses to eliminate backdoors and hidden persistence mechanisms.

When you engage Sirius for incident response, you are not just reacting — you are taking back control with an independent, surgical, and uncompromising defense mindset.
