Sucuri Security

How do you explain web application security to a client without getting too technical? A web application accepts input, processes requests, manages user sessions, accesses data, and lets people perform actions. Each interaction needs protection. Web application security protects how a website or web app behaves and interacts with users, data, and underlying systems, so vulnerabilities can’t be used to gain unauthorized access or manipulate the application. #WebsiteSecurity #WebSecurity

Authentication answers “Who are you?” Access control answers “What are you allowed to do?” When access controls fail, users may be able to access data or perform actions beyond their intended permissions. Learn how broken access control happens and how to reduce the risk. #WebSecurity sucuri.net/guides/what-is-br…

Could one of your #WordPress sites still be running a vulnerable plugin version? Our latest roundup covers high-risk vulnerabilities, including issues that can be exploited without authentication. Check affected versions and available fixes. #WordPressSecurity blog.sucuri.net/2026/10/vuln…

Website security isn’t something you configure once and cross off the list. Websites change. Users change. Plugins and integrations change. Keep reviewing what you need to protect, what has changed, and where unnecessary exposure can be removed. academy.sucuri.net/courses/u…

When was the last time you looked at everything connected to your website, not just the website itself? Plugins, users, integrations, staging sites, subdomains, APIs, backups... Which one tends to get forgotten?

Deactivating something doesn’t always remove it. Old plugins, staging sites, administrator accounts, API credentials, subdomains, and integrations can stay around long after their original purpose is gone. That means there’s still something to maintain, update, monitor, or protect. A useful website security habit is surprisingly simple: periodically review what’s connected to your website and ask whether it still needs to be there. If not, remove it properly!

A vulnerability is a weakness. A threat is something that could take advantage of it. An exploit is how that weakness gets used. Knowing the difference makes it easier to understand what actually needs attention when a security issue is reported. academy.sucuri.net/courses/u…

An API makes it easier for systems to talk to each other. It also creates another access point to protect. Know which APIs your website uses, what they can access, and whether old credentials or integrations are still active. sucuri.net/definitions/secur…

You can’t reduce a website’s attack surface if you don’t know what’s in it. List your plugins, integrations, admin accounts, APIs, staging sites, subdomains, and backups. Keep what you need. Remove what you don’t. Protect what remains. blog.sucuri.net/2026/08/what…

🚧 A #WordPress security plugin is only one layer of protection! Most plugins work inside WordPress, after PHP loads.
