Question 1

What is multi-factor authentication (MFA)?

Accepted Answer

Multi-factor authentication adds a second verification step when logging in, typically a code sent to your phone or generated by an app. Research shows MFA blocks 99.9% of automated account attacks.

Question 2

Do I need a password manager?

Accepted Answer

Yes. With the average person managing over 100 accounts, unique passwords are impossible to remember. CISA and NIST explicitly recommend password managers as essential tools for home cybersecurity.

Question 3

Is Windows Defender enough for antivirus protection?

Accepted Answer

For most home users practicing safe online habits, Windows Defender provides excellent protection, consistently scoring 6/6 in independent testing. Additional paid antivirus may benefit users with higher risk profiles.

Question 4

Should I freeze my credit?

Accepted Answer

Yes. The Federal Trade Commission calls credit freezes the best protection against identity thieves opening new accounts in your name. Credit freezes are free at all three major bureaus since 2018.

Question 5

How much does home network security cost?

Accepted Answer

HardEdge Security offers a free 30-minute consultation, security assessments for $150, and full network security installations ranging from $1,500 to $3,000 depending on home size and complexity. Many security improvements like enabling MFA and freezing credit are completely free to do yourself.

Question 6

Do I need a VPN for my home network?

Accepted Answer

For most home users, a VPN provides limited security benefit since most web traffic is already encrypted with HTTPS. VPNs are most useful on public WiFi networks. A properly configured router with a hardware firewall provides more comprehensive home network protection.

Question 7

How do I secure my smart home devices?

Accepted Answer

Key steps include: change default passwords on all devices, enable two-factor authentication on device accounts, put IoT devices on a separate guest network, keep firmware updated, and only buy devices from reputable manufacturers who provide security updates.
