Digital Forensic Analysis Services (DFIR & Incident Response)
Maybe it’s obvious, files encrypted, a ransom note, accounts locked. Maybe it’s subtle, login alerts at 3am, an employee behaving strangely, a financial transaction you don’t recognize. Either way, the worst thing you can do right now is guess.
DFIR is the structured process of determining exactly what happened, what was accessed or exfiltrated, how the attacker got in, and what you need to do immediately to stop further damage. At Pentest Testing Corp, we approach every DFIR engagement the same way we approach penetration testing: attacker-mindset analysis, evidence-first methodology, and reporting clear enough for executives and detailed enough for your legal team.
Remote incident triage starts from $2,500. If you’re dealing with an active incident, don’t wait; contact us now.
You’re Here Because Something Is Wrong
Most organizations don’t discover they’ve been breached through their own detection tools. They hear it from a bank, a customer, a regulator, or a threat actor demanding payment. By then, logs may have rotated, attacker tooling may have been removed, and the window for clean evidence collection is narrowing fast.
Speed matters. But so does doing it correctly. Rushing to wipe and rebuild without a proper investigation means you may miss persistent backdoors, misidentify the entry point, or destroy evidence you’ll need for insurance claims, regulatory disclosure, or legal proceedings. That’s the problem DFIR solves, clarity under pressure, without sacrificing the integrity of the evidence.
What a DFIR Investigation Actually Does
Our investigations are built around five areas that need to happen simultaneously, not sequentially.
Evidence Preservation
Before anything else, we establish a preservation protocol. Rebooting a compromised host, clearing logs, or reimaging a device before acquisition permanently destroys forensic value. We guide your team on what not to touch and capture volatile memory, disk images, and log exports in a forensically sound, hash-verified manner.
Compromise Scoping
We determine the actual blast radius. Is this contained to a single account, or has lateral movement spread across your environment? Are cloud identities compromised? Is there active persistence, a scheduled task, a C2 beacon still calling home? Scope defines the true extent of the incident, not just what’s visible on the surface.
Timeline Reconstruction
We build a chronological record of attacker activity: when access was first obtained, which systems were touched, what data was staged or moved, and when the intrusion likely began, often weeks before detection. This timeline is the backbone of your incident report and essential for any compliance disclosure.
Containment Guidance
Containment runs parallel to investigation, not after it. We provide prioritized steps, what to isolate, which credentials to rotate, which cloud tokens to invalidate, while analysis continues. Waiting until the investigation concludes to contain an active threat is a costly mistake.
Executive and Technical Reporting
You receive two outputs: a technical forensic package for your security team and a clear executive summary for leadership, legal, and your board if needed. Both are written with the understanding that this documentation may appear in front of regulators or in litigation.
The Incident Types We Investigate
How the Investigation Works, Step by Step
1. Confidential Intake and Scoping
We start with a scoping call to understand what’s been observed, which systems and accounts are in scope, and what the investigation needs to produce, whether that’s operational containment, legal documentation, or regulatory disclosure support.
2. Evidence Preservation
We guide your team through immediate preservation steps and, where required, perform remote forensic acquisition of disk images, memory captures, and log exports.
3. Analysis and Timeline Construction
We work through endpoint artifacts, identity logs, cloud telemetry, and network data to build the attack timeline and map attacker activity across your environment.
4. Containment and Eradication
Prioritized containment steps are delivered in parallel with the investigation. You’re not waiting until the end of a multi-week analysis to start reducing your exposure.
5. Reporting and Debrief
A complete forensic evidence package and executive summary are delivered. We walk your team through findings and answer questions from legal, compliance, or leadership directly.
What You Receive at the End
- Written attack timeline, referenced to forensic evidence
- Forensic evidence package with hash verification records
- Compromise scope assessment covering affected systems, accounts, and data
- Indicators of compromise (IOCs) where identified
- Prioritized containment and eradication recommendations
- Executive summary suitable for board, legal, or regulatory reporting
- Optional: formal evidence handling documentation for insurance or litigation support
DFIR as Part of a Mature Security Program
DFIR doesn’t exist in isolation. Organizations that respond most effectively to incidents are the ones that have already done the foundational work, penetration testing, compliance readiness, and security hardening. If you’ve worked with us on a web application penetration test or compliance risk assessment, our DFIR team already understands how to apply attacker-mindset thinking to your environment. The transition from proactive testing to reactive investigation is seamless.
Post-investigation, we help you understand how the breach occurred within your broader security posture, and whether a formal penetration test, a compliance gap assessment, or targeted hardening should be the next step.
Why Organizations Trust Pentest Testing Corp for DFIR
Pentest Testing Corp has delivered security engagements to more than 257 organizations across 30+ countries, with over 6,000 validated vulnerabilities identified across web, API, mobile, cloud, and network environments. Our CEO, Md. Shofiur, holds certifications in Digital Forensics, Windows Security & Forensics, Ethical Hacking, and ISO/IEC 27001, and is a top-rated cybersecurity professional on Freelancer.com.
That background matters in DFIR. Forensic analysis without attacker-mindset thinking misses persistence mechanisms, misidentifies entry points, and underestimates scope. We conduct investigations the same way we conduct penetration tests — by thinking like the attacker who was already inside.
Pricing: Remote triage from $2,500 | Investigation + containment from $6,500 | Full DFIR engagement from $12,000+ (custom scope)
