Incident Response & Digital Forensics Services

Incident response is the process of containing, investigating, and recovering from an active cyberattack — such as ransomware, a data breach, or unauthorized access. Digital forensics is the technical investigation that follows, establishing exactly what happened, how the attacker got in, and what data, if any, was affected. PS INFOSEC supports both organizations currently facing a suspected incident and those building incident response readiness before they need it.

What Is Incident Response?

When a security incident happens — ransomware encrypting files, unauthorized access to a system, or signs of data exfiltration — the first hours matter. Incident response is the structured process of containing the threat to stop it from spreading further, investigating what happened and how, and guiding recovery decisions, all while preserving evidence in case legal, insurance, or regulatory follow-up is needed later.

Digital forensics is the deeper technical investigation layer within incident response — reconstructing the attacker’s actions, identifying the initial entry point, and determining the scope of data or system impact with a level of rigor that can withstand external scrutiny if required.

What We Offer

Incident Response Readiness Assessment

Evaluating your current detection and response capability before an incident happens, so gaps are found proactively

Active Breach Containment & Response

Rapid containment to stop an active threat from spreading further across your environment

Ransomware Incident Response

Structured containment, impact assessment, and recovery guidance specific to ransomware incidents

Digital Forensics Investigation

Reconstructing attacker activity and establishing root cause with evidence-grade rigor

Malware Analysis

Analyzing malicious files or code found during an incident to understand their behavior and impact

Log Management Review

Reviewing available logs to reconstruct the incident timeline and identify what data or systems were affected

Our Incident Response Process

Why Evidence Handling Matters From the First Hour

A common, costly mistake during a suspected breach is to immediately power down affected systems or start deleting suspicious files — understandable instincts that can permanently destroy the forensic evidence needed to understand what actually happened, and can complicate insurance or regulatory follow-up later.

Every investigation we conduct follows evidence-handling practices that preserve the ability to reconstruct events accurately, whether the outcome is purely internal remediation or needs to support a legal, insurance, or regulatory process.

Frequently Asked Questions

We think we're experiencing a breach right now — what should we do?

Contact us immediately rather than powering down affected systems on your own — shutting systems down can destroy the forensic evidence needed to understand what happened and can complicate recovery. Isolate affected systems from the network if you can do so safely, and get in touch as the next step.

What is the difference between incident response and digital forensics?

Incident response is the broader process of containing and recovering from an active incident. Digital forensics is the detailed technical investigation within that process — reconstructing exactly what happened, with a level of evidentiary rigor that can support legal, insurance, or regulatory follow-up.

What is a ransomware incident response?

A structured process to contain the ransomware's spread, assess what was encrypted or exfiltrated, and guide recovery decisions — including evaluating whether backups can be used for recovery, as part of a broader response plan.

Can you help us prepare before an incident happens?

Yes — an Incident Response Readiness Assessment evaluates your current detection and response capability proactively, identifying gaps before they're tested by a real incident.

Do you provide reports suitable for insurance or regulatory purposes?

Yes — our post-incident reports are documented with the evidence handling and detail needed to support legal, cyber insurance, or regulatory follow-up where required.
