Many underestimate the importance of enforcing regular security updates and a long-term site maintenance plan. WordPress websites don’t maintain themselves. Between frequent core update releases and the ever-present, ever-evolving threats to your site’s security, investing in a maintenance strategy assures that your investment is protected.

In the words or WordPress, “If a vulnerability is discovered in WordPress and a new version is released to address the issue, the information required to exploit the vulnerability is almost certainly in the public domain. This makes old versions more open to attack, and is one of the primary reasons you should always keep WordPress up to date.”
