Biggest opportunity: Swap “login security” and “site health” for “hardening” and “harden”. “login security” isn't earning its slot: you're not in the first 24 results for its own search. “hardening” sits at #4 untagged, close enough for a declared tag to move it up. “site health” isn't earning its slot: you're not in the first 24 results for its own search. “harden” sits at #5 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

1.8%

of downloads still active

At least 1K of 55K lifetime downloads are still running, above its category: the median Login & Users plugin keeps 0.7%, across 1,476 plugins.

Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Login & Users plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

This plugin shipped 7 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

    The SiteLock Security WordPress plugin is a lightweight WordPress security tool aimed at giving site owners essential protections with minimal performance impact. It focuses on baseline hardening (e.g., blocking unsafe scripts and tightening directory permissions) and login security (e.g., brute-force protection, session timeouts, and strong password enforcement) right from your WordPress dashboard. Cloud-powered scans and on-demand checks help you monitor your site’s status without consuming server resources.

    Since the start of the service SiteLock is not able to connect to my (verified) domain and verify the SSL certificate. Support reactions are far from satisfying.

    They will show false positives for Google Analytics tag, then charge you to remove it, then send you an email saying they were wrong and it was a false positive and that they didn’t actually remove any malware, but won’t refund your money.

    With my extensive travels, festival reviews and listing of nearly 1,000 Ohio festivals, it’s impossible for me to constantly check the safety of the thousands of outgoing links found on my website. That’s why I’m thankful when SiteLock warns me about a malicious site so that I can quickly remove the bad link before my readers click on it.

    SiteLock employees definitely understand customer service. When I signed up for Sitelock’s website security service, I was also in the middle of changing web hosting companies, transferring my domain name and getting my website redesigned in the wake of my previous website having been hacked and rendered useless. Steve (my SiteLock security consultant) went the extra mile and helped with some things that weren’t even his responsibility.

    Our website had been compromised previously, each time causing reduced search engine traffic and a lot of time and money to fix the issues. And, we still could not figure out how it was happening. The SiteLock engineers found the holes and thoroughly cleaned our site. Now with SiteLock’s daily scanning…, our site is secure!!

    I own a wedding business in Las Vegas. I chose to use SiteLock for my site after experiencing a virus on my website a year ago. The previous virus was a nasty self-replicating one that brought my business to a complete stand still. I did not want to take the chance that the site would be hit again by unscrupulous hackers. I chose to incorporate Sitelock into my current website and have been grateful that I did.
