Other than a basic firewall, which most hosting companies offer, what type of anti hack measures are used to ensure the site stays online and safe from cyber thieves and hackers?
A managed hosting company may offer any of the following security measures to protect your managed hosting site from attacks, including virus scanning, spam filtering, firewall configuration and operating system updates in addition to standard physical data center security measures.
In addition to standard preventative security measures, some hosting companies offer one-time add-on services that harden your server against possible threats. These add-on services can include a security audit/scan for your server among other preventative procedures.
