If you host your website with PLiKhost, you already benefit from Imunify360, a powerful security platform that helps protect your hosting environment from a wide range of cyber threats.
However, many website owners still ask an important question: if Imunify360 is already active, is SiteLock really necessary?
The answer depends on the type of protection you need. While both solutions focus on website security, they protect different layers of your online presence. As a result, using them together creates a much stronger defense than relying on either solution alone.
In this guide, we’ll explain the differences between Imunify360 and SiteLock, as well as when it makes sense to use both.
🔒 What Is Imunify360?
Imunify360 is a security solution installed at the server level by PLiKhost. It provides:
-
Real-time malware detection across all accounts
-
Intrusion detection and prevention system (IDS/IPS)
-
Hardened PHP
-
Brute-force protection for server services (FTP, SSH, SMTP)
-
Proactive defense using AI-powered heuristics
Think of Imunify360 as the security team protecting an entire apartment complex. It monitors the building, blocks intruders, and helps keep every resident safe from common threats.
🛡️ What Is SiteLock?
SiteLock, on the other hand, works on the website level, and offers:
-
Daily malware scanning of your specific site
-
SMART automatic malware removal
-
Google blacklist monitoring
-
Website reputation protection
-
Web Application Firewall (WAF) at the DNS level
This is your personal home alarm system, scanning and protecting your individual unit, even from threats that make it past the front gate.
⚖️ Imunify360 vs SiteLock — Key Differences
| Feature | Imunify360 (Server Level) | SiteLock (Website Level) |
|---|---|---|
| Server-wide malware protection | ✅ Yes | ❌ No |
| Per-site malware scan & cleanup | ❌ Limited | ✅ Yes (SMART auto clean) |
| Google blacklist monitoring | ❌ No | ✅ Yes |
| Web Application Firewall (DNS-based) | ❌ No | ✅ Yes |
| Works if WordPress is compromised | ❌ May miss some threats | ✅ Yes |
| File-level restoration & alerts | ❌ No | ✅ Yes |
🧠 Why Use Both?
Here’s the reality:
-
Imunify360 stops many attacks before they reach your website, but it doesn’t monitor your SEO, Google status, or your WordPress plugins/themes specifically.
-
SiteLock catches what slips through—and helps you recover faster if you’re hit.
✅ Imunify360 defends the server.
✅ SiteLock defends your website.
🔧 Real-World Example
A customer uploads a vulnerable WordPress theme.
Hackers inject spam links into just that one site.
-
🧱 Imunify360 might not flag it if the behavior isn’t “server-level malicious.”
-
🔎 SiteLock will detect the spam links in your pages, auto-clean the infected file, and alert you.
-
📉 Without SiteLock, your domain might get blacklisted by Google before you even notice.
