Any site is vulnerable to one degree or another. This is not a theory, but an axiom. Both government and commercial sites and private sites are hacked.
We will not analyze why and how this is done. Enough has been written about this on many other sites. We will tell you what we can do for you.
First of all, we can strengthen the protection of your site. This is especially true for sites based on popular free CMS. Having made an in-depth analysis of your site, we will identify the most vulnerable spots and take measures to eliminate them.
If your site is already infected, we can “cure” it. This is relevant if a hack was noticed on time and only malicious code was posted on the site, which we will definitely find and remove. But there may be nothing to cure if the fact of hacking was discovered too late and the attackers managed not only to inject malicious code, but also to damage or completely delete some files. In this case, it may not be possible to restore the operation of the site without a backup copy.
