It's crucial that you have the latest version of WordPress, as well as all the plugins and themes you use on your site. Non-updated plugins and CMS are the most common cause of site hacking. WordPress is actually a pretty secure CMS, but only when updated.
What is important and what gives you security is the fact that it is very often updated and improved. Security is always at the forefront of the community of developers who develop it. WordPress is constantly updating its system, thus closing the security vulnerabilities found in older versions. These security vulnerabilities can lead to the misuse of your site, through which viruses, spam, etc. can spread, and you are not even aware of what is happening under the hood.
During the update, our developers take care of everything. Site maintenance includes protecting the website and server, updating the PHP version, updating plugins and themes, offline backup of databases and files, monitoring the operation and availability of the website, updating content, monitoring and protection against malware. The service also includes neutralizing security risks, such as site intrusions, spamming, blocking content and other security issues.
The cost of maintenance depends on the number of changes and the needs of the website itself. We have maintenance packages on an annual level (contract for a year) or as needed.
