Laptop Security Features to Check Before You Buy (and Set Up on Day One)

Forrest Kritzer

The safest new laptop pairs a currently supported OS with working full-disk encryption and a saved recovery key, unique passwords plus MFA or passkeys, automatic updates, a tested backup, and sensible physical habits like a lock slot or privacy screen. No single feature — biometrics included — makes a laptop unhackable or theft-proof.

Buying a new laptop is also the best moment to set its security up correctly, since most of the useful protections are things you configure in the first day, not things you buy separately. Below is what to check on the hardware side, and what to switch on before you start using the machine for anything sensitive.

1. Built-in Hardware Security


2. Encryption and Recovery Keys

Turning on full-disk encryption is one of the highest-value steps you can take, and on most current laptops it's already partly done for you.

Encryption also isn't a backup, and it doesn't stop malware from reading files during an already-unlocked, authorized session — its main purpose is protecting stored data against unauthorized access, especially when the device is powered off; screen locking is a separate control.


3. Accounts, Passwords, and Passkeys

Use a unique password for your main account plus multi-factor authentication, and enable passkeys where supported. A passkey lets you sign in with your face, fingerprint, or device PIN instead of typing a password; depending on the service, the passkey may stay local to the device or sync through a credential manager, or be stored on a security key or phone, so check where each one is stored and keep a recovery option available. Setting a short auto-lock timeout for the screen is a simple habit that limits the window during which a lost or stepped-away-from laptop is usable by someone else. If the laptop is issued and managed by an employer or school, follow their IT policy rather than removing any management profile it arrives with.


4. Supported OS and Malware Protection

Buy a laptop that ships with, or can run, a currently supported operating system. If you're moving from an older Windows 10 machine, note that regular support ended October 14, 2025, and eligible users can enroll in a temporary consumer Extended Security Updates program for devices staying on Windows 10 — that's a bridge for an existing device, not a reason to set up a new laptop on an unsupported OS.

On Windows, the built-in Windows Security app runs Defender's real-time protection and lets you check update and scan status. If you install a compatible third-party antivirus, it will typically switch Defender off automatically — avoid running two real-time scanners at once, and avoid disabling protection or adding broad exclusions just to get software to run. There's no requirement to buy paid antivirus, and no software offers perfect protection.


5. Backups You've Actually Tested

On Mac, Time Machine automatically backs up files and can recover deleted or older versions. iCloud sync is convenient but does not replace a separate backup with recoverable versions: deletions can propagate through sync, and losing account access can affect access to cloud copies. Whatever backup method you use, periodically test that you can actually restore a file, and keep at least one backup copy away from the laptop itself — not in the same bag — so a single theft or spill doesn't take out both.


6. Physical Security Habits


7. Insurance for Loss or Theft

Renters or homeowners policies often extend to personal electronics, but coverage details vary by policy. Per NAIC guidance, check exclusions, deductibles, whether payout is replacement cost or depreciated actual cash value, and any per-item limit on electronics. Keep a simple inventory with serial numbers, receipts, and photos. Not every scenario — accidental damage, business use, or loss away from home — is automatically covered, so confirm specifics with your insurer rather than assuming.


8. Buying and Setup Checklist

Area What to check
Lock slot Confirm the specific model has one if you plan to use a cable lock
Biometrics Fingerprint reader or IR camera present; PIN/password fallback set to something strong
TPM For Windows, TPM 2.0 supported and enabled; Macs use Apple’s hardware security architecture
OS support Ships with, or can run, a currently supported operating system
Encryption Device Encryption/BitLocker or FileVault turned on; recovery key saved separately
Accounts Unique password, MFA or passkeys enabled, short auto-lock set
Backups Automatic backup configured and a restore actually tested

Bottom Line

A laptop's security is mostly determined by what you check at purchase and configure on day one, not by any single marketed feature. Check the platform’s security hardware and a compatible lock slot if you need one, buy a currently supported OS, then spend the first session turning on full-disk encryption with a safely stored recovery key, setting a strong password with MFA or passkeys, confirming update and backup settings, and adding physical habits like a cable lock or privacy screen where they fit your routine. None of these steps individually guarantees safety, but together they cover the realistic risks — theft, malware, and data loss — far better than any one built-in feature on its own.
