If there’s one unsettling truth that modern-day business owners need to accept, it’s that cyberattacks aren’t really a matter of “if”, but more a matter of “when” they will happen.
It doesn’t make a difference if you’re the founder of a startup with 15 employees or an enterprise with 15,000, the fact remains that hackers, phishing schemes, and ransomware attacks don’t discriminate. If there is a glaring vulnerability and a gap to be exploited, they will exploit it.
So when that time comes, how will you react? What’s your strategy for minimizing the damage and making sure your company gets back on track as soon as possible? In most cases, how you respond in the first 24 hours can make all the difference between a quick recovery and a drawn-out crisis.
Why the First 24 Hours Are Crucial
In many ways, you can use the analogy of a house for a cyber attack. The quicker you respond to it, the less damage it does. Those first few hours aren’t about restoring everything to normal. They’re about damage limitation, containing the threat, preserving evidence, and ensuring your business can continue to operate.
That’s why incident response is one of the first cybersecurity services that you need to implement so that you can have a clear roadmap for what to do when a crisis hits. Instead of scrambling, you know who’s responsible for what, which systems to isolate, and how to communicate with employees, customers, and regulators.
Without that structure, valuable time is lost, and attackers will have free rein to move through your systems and steal sensitive data. With a plan in place for those crucial first 24 hours, you can act decisively, limit the fallout, and set the tone for recovery.
Step 1: Identify and Contain the Attack
The very first step is simple. You need to stop the bleeding. The moment a potential breach is detected (whether through monitoring tools, employee reports, or unusual system behavior), you must confirm that an attack is underway and then take rapid action to contain it. How you do that depends on the type of attack you’re facing, but some examples include:
- Disconnecting affected machines from the network
- Locking down compromised user accounts
- Shutting off remote access until you understand the situation
Don’t worry about fixing everything here. It’s far more essential to stop the attack from causing further damage and spreading. That’s your main priority.
Step 2: Activate Your Incident Response Plan (If You Have One)
If you have an incident response plan, now is the time to put it into action. This should clearly outline who needs to be notified first, such as IT, legal, leadership, and possibly external cybersecurity services. It also needs to clarify who exactly has decision-making power in these pivotal moments.
There usually won’t be time to go to the board or make hour-long Zoom calls. You need someone with authority and expertise to make decisive calls quickly. When everyone knows their role and has been briefed, you save hours of back-and-forth, and that can make all the difference.
Step 3: Preserve Evidence
In the heat of the moment, it’s easy to panic and focus all of your energy on preventing the attack and stopping the bleeding. In this chaos, it’s tempting to start wiping drives immediately and affected systems, but doing so could erase valuable evidence.
Logs, files, and even infected machines provide valuable insights into how the attack occurred, where it originated, which systems were compromised, and whether sensitive data was accessed. Be sure to conduct digital forensics to determine exactly what happened. Without this information, you may be able to stop the immediate problem but remain vulnerable to a repeat attack in the near future.
Step 4: Communicate Internally (and Carefully)
One of the fastest ways to make a bad situation worse is by communicating poorly. Rumors, panic, and confusion spread quickly around your company if your team doesn’t know what’s going on, but they have heard whispers that something is wrong.
Because of this, you need a clear plan for who and how you will communicate the breach. Depending on the severity and the stage of the attack, it’s usually a good idea to inform all employees in clear, simple terms. Explain if there will be any changes to their workflow (for example, new login rules or systems being offline), and then reassure them that steps are being taken to secure the business.
At the same time, avoid over-communicating sensitive details. Not every employee needs to know the technical specifics or the full scope right away. Keep the messaging consistent and professional.
Step 5: Decide on External Notifications
If you’ve suffered a significant breach and customer data has been affected, you may be obligated to notify customers, regulators, or even law enforcement within a specific time window.
This is where having legal counsel by your side, as well as a cybersecurity provider, will pay dividends. You’ll need to carefully balance transparency with caution, as these types of announcements can cause panic and confusion rapidly.
Whatever you do, just remember that it’s always best for people to hear it from you first. The last thing you want is for them to read about the breach in the news before you have a chance to disclose it.
Step 6: Begin Recovery with a Long-Term View
Once the immediate attack is contained, it’s time to start the recovery process. This includes restoring systems from clean backups, patching vulnerabilities, and bringing business operations back online.
This is also an essential time for everyone to come together for a learning opportunity. Every cyber incident presents an opportunity to strengthen your defenses. Ask questions like:
- How did the attack get through?
- Were there missed warning signs?
- Did the team effectively follow the incident response plan?
- What gaps need to be closed moving forward?
Answering these questions will provide you with more information about how the attack unfolded, and, more importantly, how you can close those gaps and minimize the likelihood of it happening again.
Final Word
Cyber attacks are no longer rare, once-in-a-decade events. They’re an everyday risk for businesses of all sizes across all industries. And while you can’t predict exactly when an incident will happen, you can control how prepared you are to respond.
If you haven’t already, now is the time to put your plan in place. Work with cybersecurity experts who can help you build, test, and refine an incident response playbook before you ever need it.
It will never be about avoiding every cyber threat, because that’s not possible. It’s about responding so effectively that your business comes out stronger on the other side.
