原文外掛簡介

Your Site Deserves Real Protection
You built your WordPress site to grow your business, share your ideas, or connect with your community. You shouldn’t have to become a security expert to keep it safe.
BitFire stops hackers, bots, and malware automatically so you can focus on what matters: running your site. And when you have a question, a real person on our US-based support team is here to help, 12 hours a day.
How BitFire Keeps You Safe
Most security plugins wait until something goes wrong and then try to clean up the mess. BitFire works the other way around: it stops threats before they ever reach your site.
Think of it like a lock on your front door versus a camera that records a break-in. BitFire is the lock.
Our AI-powered scanner watches your files and traffic in real time, catching new threats that other plugins miss because they are still waiting for someone to write a rule for it.

“Traditional firewalls allow everything by default and react to known threats. BitFire flips that: it verifies traffic first and only lets the good stuff through.”

Key Features
What BitFire Does For You (Free)
Stops Bots Automatically
Spam bots, scrapers, and scanners get blocked before they waste your server resources or fill your forms with junk. No CAPTCHAs, no puzzles for your visitors.
Scans for Malware
BitFire checks every file on your site against a database of over 20 million known-good files. If something does not belong, you will know about it.
Shows You Who is Visiting
See every request to your site in real time: where visitors are from, what browser they are using, and whether they are a real person or a bot. No more guessing.
Protects Your Login Page
Brute-force attacks, password stuffing, and login bots are stopped cold. Your admin area stays locked down.
Tells Real People from Fake Browsers
BitFire verifies visitors with 99.7% accuracy, 50 times faster than Cloudflare’s challenge pages. Real visitors never notice. Bots get stopped instantly.
Blocks Known Bad Actors
Over 300,000 known malicious IPs are blocked before they can even connect to your site.
What You Get with BitFire Pro
Everything in Free, plus the protections that stop even zero-day attacks on vulnerable plugins and themes:
Runtime Protection (RASP)
BitFire is the only WordPress security plugin with Runtime Application Self Protection. It watches what your plugins and themes are actually doing and stops anything suspicious:

A plugin tries to create a secret admin account? Blocked.
Malware tries to edit your PHP files? Blocked.
A hacked plugin tries to phone home to a malware server? Blocked.
Code tries to redirect your visitors to a scam site? Blocked.

BitFire has blocked 100% of critical WordPress zero-day vulnerabilities since 2022, with zero new rules required.
A+ Rated Web Application Firewall
Independent testing by Cloudbric rated BitFire’s WAF at 94% (A+). See how that compares:

BitFire [PRO]: 94% (A+)
Ninja Firewall [PRO]: 67% (D)
WordFence [PRO]: 41% (D)
MalCare [PRO]: 34% (F)
iThemes Security: 2% (F)
Shield Security [PRO]: 2% (F)
SiteGround Security: 2% (F)

AI-Powered Malware Analysis
When the scanner finds something suspicious, BitFire’s AI analyzes it in real time to determine if it is actually malicious or just unusual code. Pro users get results in about 2 minutes. Free users can submit files for batch analysis.
Automatic Security Headers
BitFire learns which domains your site uses (Google Fonts, your CDN, analytics, etc.) and automatically sets up Content Security Policy headers that earn an A+ rating. This protects your visitors from cross-site scripting and redirect attacks without you having to configure a thing.
30 Days of Traffic History
Look back through a full month of traffic data to investigate issues, spot patterns, or just understand how your site is being used.
Real Human Support
This is what makes BitFire different from the big-name security plugins: when you need help, you talk to a real person.
Our US-based support team is available 12 hours a day. No ticket queues that take days. No chatbots. No copy-paste answers. Just experienced people who will make sure your site is secure.
Whether you need help with setup, have a question about a block, or want someone to look at a suspicious file, we are here.

How BitFire Compares
BitFire vs WordFence
WordFence is a solid product with a large team writing custom rules for known vulnerabilities. But there are two things you should know:

Free WordFence delays protection by 30 days. When a new vulnerability is found, paying WordFence customers get the fix immediately. Free users wait a full month. If your site is vulnerable, it will almost certainly be attacked before the free patch arrives.

WordFence relies on knowing about attacks in advance. With over 10,000 known WordPress vulnerabilities and fewer than 200 signatures, they simply cannot cover everything. BitFire’s RASP does not need to know about an attack in advance. It watches what code is actually doing and stops anything malicious, even brand-new attacks nobody has seen before.

Whatever security solution you use – we strongly recommend only using the paid version for all important work.

Why Do Other Plugins Focus So Much on Cleaning Up Malware?
Good question. Notice how much other security plugins charge for malware removal and how much of their marketing is about finding infections?
A security plugin that does its job well should not need to clean malware off your site very often. If a plugin spends most of its energy on cleanup, that tells you something about how well it prevents attacks in the first place.
BitFire focuses on keeping malware off your site so you do not need to pay someone to remove it.
Privacy / Monitoring / Data Collection
We take your privacy seriously. Here is exactly what BitFire does with data:

Traffic inspection. BitFire inspects web traffic to your site to identify threats. Sensitive data like passwords and credit card numbers is automatically replaced with redacted in logs. You can add additional fields to filter in the settings.

Error reporting. If BitFire encounters a software error, it can send a report to our development team so we can fix it in the next release. No visitor data is included in these reports.

Malware hash checking. BitFire sends tiny numeric fingerprints (64-bit hashes) of your files to our hash server to check them against our database of known-good files. For example, a file might hash to the number 812612388126487. We never see your actual file contents, and your hashes are never stored on our servers.

Local data storage. All log data and configuration files are stored locally on your server in a hidden, randomly-named directory under wp-content/uploads/. This directory is protected by an .htaccess file and is not accessible from the web.
