What to Do When Every Second Counts

Cybersecurity incidents move fast. Even brief outages shake customer certainty. When your business treats incident response as a practiced protocol, you can keep control and contain the impact. 

This guide shows you what to expect in a breach and the disciplined response you can run to restore operations faster.

What Is Cybersecurity Incident Response?

Cybersecurity incident response is the operational discipline that moves your business from the first alert to full recovery without stalling operations.

Beyond recovery, it turns each incident into concrete fixes that lower future risk.

A Business Continuity Tool, Not Just a Tech Fix

Effective incident response aligns IT, security, compliance, and executive leadership. It’s a critical piece of business resilience, especially when threats are more frequent and complex than ever.

Why Incident Readiness Is a Strategic Advantage

Unfortunately, you can’t prevent every attack. Fortunately, you can decide how you’ll respond.

For company leadership, such as the COO, CFO, or CEO, that response has direct business implications:

  • Downtime halts productivity
  • Regulatory fines hit the bottom line
  • Reputation damage lingers for years
  • Client churn increases as trust erodes

Organizations that respond swiftly and effectively tend to come back stronger. That’s what strategic readiness enables.

Want to assess your current posture? A breach risk assessment is a great first step.

What Triggers an Incident Response?

Not sure when to call in your incident response team? Here are common scenarios that should sound the alarm:

  • Suspicious network activity or traffic spikes
  • Successful phishing attempts compromising credentials
  • Ransomware or malware infections
  • Insider threats or unauthorized access
  • Compliance breaches (HIPAA, CMMC, etc.)
  • Third-party vendor exposures

The earlier you catch the issue, the faster it can be contained. That’s why our incident response team is trained to mobilize immediately, day or night.

What Are the Steps in a Cybersecurity Incident Response Plan?

RedHelm follows a proven, multi-phase incident response framework that combines precision, speed, and strategic insight.

1. Detection & Identification

Our tools and experts spot the threat, validate it, and begin documenting what’s happening. We triage alerts to separate signals from noise.

2. Containment

We isolate affected systems and accounts to stop the spread. This step is about limiting damage while preserving evidence.

3. Investigation & Diagnosis

Our cyber forensic specialists analyze the breach based upon your organizational goals to understand items such as:

  • How the attacker got in
  • What systems or data were accessed
  • Whether persistence mechanisms remain
  • Data Exfiltration

4. Eradication

Once we know the source, we remove malware, disable backdoors, patch vulnerabilities, and eliminate residual threats.

5. Recovery

We safely restore systems from clean backups and verify that everything is secure before returning to full operations.

6. Lessons Learned

After the dust settles, we provide a detailed post-incident report, recommend next steps, and help strengthen your defenses.

Case Study: Stopping a Sophisticated Phishing Scam

In a recent incident, RedHelm responded to a coordinated phishing campaign that used polymorphic links to target both employees and customers. The links were especially dangerous because they adapted based on the victim’s browser, making them difficult for traditional detection systems to catch.

To contain the threat, our team launched a multi-pronged investigation:

  • Rapid Detection began with asset discovery, and inventory.
  • Technical Analysis involved sandbox testing to safely study malicious emails and attachments.
  • Pattern Recognition helped the team establish reliable Indicators of Compromise (IOCs).
  • Using those IOCs, they conducted an enterprise-wide hunt for evidence of compromise across customer environments.
  • They engaged directly with affected customers, particularly those without Endpoint Detection and Response (EDR) solutions, to contain and remediate any exposure.
  • Finally, RedHelm shared actionable threat intelligence with all customers, a move that protected other environments and demonstrated RedHelm’s commitment to transparency.

As a result, multiple customers were identified and supported before full compromise occurred. The attack became a teaching moment: environments without EDR were the most vulnerable, reinforcing the value of layered defenses and proactive communication.

Checklist: Are You Ready to Respond?

You may not need incident response today, but when you do, you’ll want to have the right partner and plan in place. Here’s how to know if you’re ready:

  • You have a documented incident response plan.
  • Your staff knows their roles during a breach.
  • You’ve tested your backup and recovery processes.
  • You know who to call, internally and externally.
  • You’ve conducted a breach risk assessment in the past year.
  • Your cyber insurance requirements are aligned with your IR process.

If you answered “no” to any of these, you’re not alone. Let’s fix that.
