Digital Forensics For The Rest Of Us

Digital forensics isn't just for Fortune 500 companies. Learn what DFIR actually means, how Velociraptor delivers enterprise-grade threat hunting at 85% less than CrowdStrike, and why 24/7 incident response matters.

What DFIR Is (In Plain English, Not Jargon)

Let's start with the acronym that security people throw around: DFIR = Digital Forensics and Incident Response

Still unclear? Let me translate to normal human language.

Digital Forensics: CSI for Computers

Digital forensics is like CSI: Miami, except the crime scene is your computer/server/cloud infrastructure, and the evidence is files, processes, network connections, and memory dumps.

What digital forensics answers:

• Who: Which user account was compromised?
• What: What did the attacker do?
• When: What time did the breach happen?
• Where: Which systems were accessed?
• How: What vulnerability was exploited?

Incident Response: What You Do When Forensics Finds Something Terrible

Forensics tells you what happened. Incident response is what you do about it.

Incident response workflow:

1. Detection: "Something is wrong" (alert fires)
2. Analysis: "How bad is it?" (forensics investigation)
3. Containment: "Stop it from getting worse" (isolate infected systems)
4. Eradication: "Remove the threat" (delete malware, revoke credentials)
5. Recovery: "Get back to normal" (restore from backup)
6. Lessons learned: "How do we prevent this?" (post-mortem)

Why DFIR Matters More Than You Think

The uncomfortable reality: Most companies don't know they've been breached until a customer reports seeing their data on the dark web, ransomware pops up, or the FBI calls.

Average time to detect a breach: 207 days (almost 7 months)

Average time to contain after detection: 73 days (over 2 months)

That's 280 days (9+ months) that attackers are inside your network.

DFIR reduces these numbers dramatically:

• Good DFIR: Detect in 24-48 hours, contain in 4-8 hours
• Great DFIR: Detect in minutes, contain in 1 hour

The CrowdStrike Pricing Problem

Now that you understand what DFIR does, let's talk about how much enterprise vendors charge for it.

The CrowdStrike Pricing Structure

Falcon Prevent (basic antivirus): $8.99/endpoint/month

Falcon Insight (EDR features): $49.99/endpoint/month

Falcon Complete (managed service): $109.99/endpoint/month

Real-world CrowdStrike cost for 100-endpoint company:

• Falcon Insight: $59,988/year
• Falcon Discover: $23,988/year
• Falcon Device Control: $11,988/year
• Total: $95,964/year

Velociraptor: Open Source DFIR That Actually Works

Let's talk about the open source tool that's making CrowdStrike nervous.

Velociraptor is an open source DFIR platform developed by security researchers frustrated with expensive enterprise tools.

Core capabilities:

• Endpoint visibility (see everything on every endpoint)
• Threat hunting (search for indicators of compromise)
• Incident response (collect forensic artifacts)
• Continuous monitoring (real-time detection)

Why Velociraptor Is Different

Query-based investigation: Instead of "detect known malware signature," it's "search for suspicious behavior patterns."

VQL (Velociraptor Query Language): SQL-like language to query endpoints for custom forensics.

Lightweight agent:

• Agent size: 10-15MB (CrowdStrike: 100-200MB)
• RAM usage: 20-50MB (CrowdStrike: 200-500MB)
• CPU usage: <1% (CrowdStrike: 2-5%)

Why You Need 24/7 Threat Hunting

Common objection: "We're a 50-person company. Why would attackers target us?"

Reality: 43% of cyberattacks target small businesses.

Why Attackers Love Small Businesses

• Easier targets (less security investment)
• Supply chain access (small company → enterprise customers)
• Lower detection (fewer security analysts)
• Ransom more affordable ($50K is attainable)

Attacks Happen Outside Business Hours

When do breaches happen?

• 62% of attacks start outside business hours
• 43% start on Friday evening (full weekend before detection)
• 31% start on holidays

Without 24/7 monitoring: Friday 11 PM ransomware → Monday 8 AM discovery → 58 hours of damage

With 24/7 monitoring: Friday 11 PM detection → Friday 11:30 PM containment → 30 minutes of exposure

The Cost Reality

CrowdStrike for 100 endpoints:

• Falcon Complete: $131,988/year
• Three-year total: $395,964

ThinSky Managed Velociraptor for 100 endpoints:

• Managed service: $48,000/year
• Three-year total: $148,000

Savings: $247,964 over three years (62% reduction)

For larger deployments (500 endpoints), savings reach 85%.
