Why Malware Detection Matters

Malware can silently infiltrate your website, compromising customer data, damaging SEO rankings, and triggering blocklist warnings that drive away traffic. Without proactive detection, threats often go unnoticed until it’s too late. Sucuri’s malware scanning tools help you identify early signs of compromise, such as hidden spam, phishing pages, or unauthorized file changes, so you can act before your site’s reputation and revenue take a hit.

Malware detection and scanning are included in all Sucuri Platform plans, giving you continuous protection with remote and server-side scanning, uptime monitoring, and customizable alerts. These features are trusted by developers, agencies, and SMBs.

Remote vs Server-Side Scanning

Sucuri offers two layers of malware detection to help you catch threats early. Remote scanning checks your public-facing site for visible issues like SEO spam and blocklist warnings. Server-side scanning goes deeper, inspecting your actual website files for hidden malware and unauthorized changes. Both are included in all Platform plans.

Remote Scanning

Remote Scanning

Sucuri is a website security company which also offers a CDN as part of its protection platform. Sucuri’s CDN provides leading-edge performance and features at a price that makes it affordable for all types of individuals and organizations.

Server-Side Scanning

Server-Side Scanning

Server-side scanning inspects your website’s core files directly on the server. It identifies obfuscated code, backdoors, phishing pages, and file integrity issues that remote scanners can’t access. It’s essential for deeper visibility and stronger protection.

Enabling Website Malware Scanning

 

1.

Add Your Site to Remote Scanner

After signing up, just type your website URL to get started. If needed, you can request a malware cleanup right away. The remote scanner is enabled instantly and will begin analyzing your site from all angles. The remote scanner captures blocklist warnings and malware visible in the source code, including conditional malware that only presents itself to certain kinds of visitors.
2.

Activate Server-Side PHP Scanner

Next, enable the server-side scanner with FTP/SFTP credentials from your Sucuri dashboard. This deep-scanning engine has full access to scanning PHP files on your server. Some malware hides itself from visitors, but it can’t hide from our server-side scanner. We see things like backdoors, phishing pages, email and DDoS scripts. Our analysts are happy to set it up for you too with a simple support request.
3.

Adjust Your Monitoring Types

By default, we offer malware and blocklist monitoring so you are alerted if we detect suspicious files or security warnings on your website. We also check your DNS records for changes. Uptime monitoring allows you to receive alerts if your website goes down for any reason. Feel free to adjust the frequency of these scans from your Sucuri dashboard settings to suit your needs.
4.

Set Up Alerts and Email Reports

Our global alerts settings in your Sucuri profile allow you to set up alerting via email, SMS, Slack, and RSS. You can also set up generic post requests to your own custom webhooks in JSON, CSV, HTML, or plain text formats. Our email reports recap data found by our monitoring engines and can be sent to you via plain text or HTML. Setting up weekly or monthly emails is an optional feature as well.

Frequently Asked Questions
