WHEN DOES IT MAKE SENSE TO SWITCH FROM GD SECURITY HEADERS?
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 GD Security Headers 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.
Cookies and Content Security Policy · No unsafe-inlineYou 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 GD Security Headers. 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.
No unsafe-inlineSupport 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.
FREQUENTLY ASKED
