Cyber Security Tip 15: What to do if you lose your laptop (or other device)

So, you’re rushing home, feeling good after grabbing your favorite coffee, only to realize you’ve left your laptop behind. You whip the car around, only to get back and find that your device has vanished. Now what? The sinking feeling in your gut is real, but here’s the hard truth: what happens next all depends on the steps you’ve taken before that device went missing.

Cybersecurity isn’t just about preventing outside attacks—it’s also about how well you’re protecting your data on the inside, including what happens if your device is lost or stolen.

If you’ve secured your laptop with strong encryption, enabled password protection, and logged out of all major applications, you’ve bought yourself some time. But that time is limited, and every second counts.

Ransomware: Don’t Open the Door for Hackers

Let’s talk about the big one first—ransomware. If your laptop isn’t properly protected and a thief gets a hold of it, your company’s data can quickly turn into a cybercriminal’s next paycheck. Here’s how it usually goes down: they gain access to your files, lock you out, and demand payment to give it back.

Ransomware attacks often begin with a single point of entry, and if your laptop is that entry, you’re at serious risk. Once inside, the attacker can easily upload ransomware, encrypt files, and hold your entire network hostage. And let’s not forget: just because you pay the ransom doesn’t guarantee you’ll get your data back. Cybercriminals aren’t exactly known for their honesty.

You can prevent this by implementing strong encryption, password-protecting your devices, and making sure you have backup systems in place. Daily backups are crucial, so even if your device is stolen, you’re not at the mercy of ransomware attackers.

Data Loss: It’s Not Just About Theft

You’re probably thinking, “I don’t store that much important data on my laptop.” Think again. Even the smallest piece of compromised data can lead to a data loss disaster. Think customer information, financial records, or even just credentials to your company’s systems.

If your data isn’t backed up, a stolen laptop could mean permanent loss of critical files. Imagine trying to rebuild customer records, financial spreadsheets, or sensitive project data from scratch. Not to mention the regulatory and compliance headaches that come with losing protected information.

Human error plays a big role here. Something as simple as leaving a laptop in a public place can lead to catastrophic consequences. And while encryption and password protection can slow down an attacker, they won’t stop them entirely. That’s why having off-site, secure backups is non-negotiable.

Data Breaches: Don’t Let Stolen Devices Become a Breach

Here’s where things get even messier. If your stolen laptop contains sensitive company data—like financials, medical records, or personal information—you could be looking at a full-blown data breach.

A breach doesn’t just mean stolen information. It means you could be required by law to notify every affected individual, deal with regulators, and potentially face legal action. Breaches like these can destroy customer trust and sink a business faster than you think.

Take, for example, a stolen laptop with employee payroll data. If that information gets into the wrong hands, it can lead to identity theft, financial fraud, and a wave of compliance issues. Now, you’re not just dealing with a lost device—you’re handling a legal nightmare.

What You Should Do Right Now

If you’ve lost your device, here are the immediate steps to take:

  1. Notify your IT department: If your business has an internal IT team or an IT provider, let them know immediately. They can change passwords, lock down accounts, and in some cases, remotely wipe the device to ensure no one can access your data.
  2. Change your passwords: Start with any financial, company-related, or sensitive accounts and move down the line. This step is critical to limit any further access.
  3. Consult with legal: If your laptop contained personal information like social security numbers, birthdays, or financial data, you might be legally required to inform affected individuals. Get ahead of this by contacting a qualified attorney to navigate these waters.
  4. Backup, encrypt, and secure: If you’re reading this and haven’t lost your device yet, this is your wake-up call. Make sure all data is encrypted, that devices are password-protected, and that remote monitoring and wiping software are installed on all company devices.
  5. Set security habits: Require a pin-code or password to access any company device after a short period of inactivity (10 minutes max). Also, get in the habit of logging out of websites and sensitive applications when you’re done using them.

Prevention is the Best Cure

The real key here is prevention. Don’t wait until a device is lost or stolen to take action. Start by securing your systems, backing up your data, and locking down your devices. If a theft does happen, you want to be in the position where your business isn’t at risk of a ransomware attack, data loss, or breach.
