Have .NET Security Questions?

Why is Microsoft IIS/.Net considered a hotbed (popular) choice for attackers?

Attackers enjoy easy access to the Microsoft OS, meaning they can develop exploits on their laptops & desktops. Without additional tools, they can easily develop, test, and execute. These attackers can then scan the internet for your website, check for vulnerabilities, and cause havoc.

Will SiteLock improve my Microsoft IIS/.NET application and website performance?

With SiteLock’s CDN (Content Distribution Network), we can help increase pagespeed, conquer Google Core Vitals, and provide your installation with the global reach it needs to perform at top speeds. If things like First Time to Byte and Cumulative Layout Shift are important to your business, our CDN is perfect for you!

Does SiteLock protect my Microsoft IIS/.NET application from zero-day exploits?

Yes, our WAF rules are updated in near real-time and provide your Microsoft IIS/.NET application instant protection against zero-day exploits, CVE’s, and other malicious threats. Blocked at the perimeter by SiteLock’s website application firewall, you’ll enjoy advanced protection with file-level patching!

How does SiteLock provide my IIS/.Net website protection without the need to install software?

As part of the easy onboarding process, you’ll be asked to provide secure FTP credentials to your IIS website.

We will then provide complete protection via the web application firewall.

If I have WordPress or a PHP application hosted on Microsoft IIS, will SiteLock protect it?

Modern stacks often include a hybrid of apps ranging from HTML, PHP, .NET, and other languages. SiteLock provides the complete protection and functionality you need to operate multiple environments.
