WHEN DOES IT MAKE SENSE TO SWITCH FROM GUARD DOG?
Four reasons people leave.
Decision triggers, not marketing. If two or more apply, your shortlist starts with the apps named below each card.
Pricing has outgrown your usage
If your usage of Guard Dog has crossed a pricing-tier breakpoint, per-unit cost is usually where alternatives diverge most clearly. Some apps in the list above carry a free tier; others are paid from day one. Compare the published plans on each alternative's page against your current bill — the gap is the only number worth acting on, and it is specific to your usage.
SiteFort Security – Malware Scanner, Firewall, Login Security & Hardening · Vigilant – 100% Free Security Suite: Firewall, 2FA, Login, Headers, Scanner…You need a feature outside the focus
Each WordPress category has a feature spectrum. The "Similar feature set" badge above marks alternatives whose feature signature most overlaps with Guard Dog. The "Category leader" badge marks apps that may approach the same category from a different feature angle — useful if you want to widen rather than narrow your toolset.
Vigilant – 100% Free Security Suite: Firewall, 2FA, Login, Headers, Scanner…Support response has slowed you down
Support quality is the hardest thing to read from a listing, and it is the most common reason a switch gets made. Read the most RECENT reviews on each alternative's profile rather than the lifetime average — recency is what tells you how the app is supported today, and trailing review velocity is the freshest signal AppRanks tracks.
