Total Defense Security Tip of the Day

The security sunset: time to upgrade that aging device?
We all love getting the maximum lifespan out of our smartphones, tablets, and laptops. It saves money, and it’s better for the planet. But there is a point in every device’s life where clinging to it becomes a significant security risk: when the manufacturer stops sending updates.
Countless electronic devices are eventually abandoned by their makers, at least when it comes to regular security and operating system patches. When your trusted phone or laptop stops receiving those critical patches and upgrades, it is essentially frozen in time, leaving it vulnerable to new threats that hackers discover every single day.
If this happens to a device you rely on for banking, email, or work, it's time to seriously consider upgrading to a newer version or an alternative that is still actively supported.
The Risk of the Abandoned Device
Think of a software update as a digital shield. Every time a major operating system (like iOS, Android, Windows, or macOS) releases a new patch, they are closing security holes that hackers have found or are actively exploiting.
When your device stops getting those updates:
- Open Vulnerabilities: You are permanently stuck with known security flaws. Any vulnerability discovered after your last update is an open door for hackers to exploit, and there is nothing you can do about it except replace the device.
- Malware Magnet: Malware, viruses, and sophisticated phishing attacks often target known, unpatched vulnerabilities. Using an unsupported device makes you a low-hanging and highly attractive target for cybercriminals.
- App Incompatibility: As developers update their apps to rely on new security features in the latest operating systems, your old device may stop being able to run critical applications like banking software, further limiting your ability to transact securely.
Your Active Solution: Check the Support Lifespan
Before you let your device become a security liability, take a moment to research its support status.
- Check the Manufacturer: Look up your device model and see when the manufacturer officially ended its software support.
- Look for Security Patches: If your operating system is still receiving monthly security patches (even if you aren't getting flashy new features), you're probably okay for now. But if all security updates have ceased, it’s a red flag.
- Plan Your Exit: If your device is past its security expiration date, start planning your upgrade. You can look for a newer version of the same device or consider alternative brands that offer longer-term support.
Don't wait until a breach forces your hand. Be proactive, check your update status, and take control of your digital security by ensuring your hardware is running fully protected software.
