Last Updated: August 22 2026

Question: How can Ontario law firms reduce website CMS hack risk and keep their CMS secure after updates?

Answer: Marketing.Legal™ helps Ontario lawyers, paralegals, and legal teams reduce CMS hack risk by using a hardened, proprietary CMS foundation with secure web-application forms instead of relying on common WordPress code, plugins, or themes that often drive breaches through patch lags, misconfiguration, and vulnerable add-ons.   In practice, we focus on ongoing update hygiene, least-privilege access, monitoring for suspicious changes, and safer content workflows so your site stays reliable even when attackers target high-visibility platforms.   If you want a quick security check for your current CMS setup and a plan for safer publishing, call (800) 551-5751.

Understanding CMS Security: A Look at Website Vulnerabilities

WordPress Accounts for 90% of Hacked Websites: Exploits Found on 2/3 of Hacked WordPress Websites, SEO SPAM on HalfIntroduction: Recent professional studies have revealed that approximately ninety percent (90%) of all compromised content management systems (CMS) on the Internet were WordPress sites.  This is a significant figure compared to Joomla (4.3%) and Drupal (3.7%), which ranked second and third respectively.  The primary reasons for these breaches include vulnerabilities in plugins and themes, misconfiguration, and inadequate maintenance, particularly in updates.

Note: Please contact Marketing.Legal™ by phone at: (800) 551-5751 to discuss any specific questions that you may have.

It was observed that only fifty-six percent (56%) of the websites examined had an up-to-date CMS at the time of the hack.  Interestingly, while WordPress constituted ninety percent (90%) of all hacked websites, most of these sites were running the latest versions.  Only thirty-six percent (36%) of the compromised WordPress sites were found to be using outdated versions.

Addressing the issue of frequent attacks, Joost De Valk of WordPress and the popular SEO plugin Yoast acknowledged the challenge, stating, “For a while, Yoast used to get hacked every month.  Being a high-profile target, we were often targeted.  We were aware of this vulnerability...”

Flaws and Pitfalls of WordPress

WordPress remains the most popular CMS, making it a prime target for hackers.  Its open-source nature and reliance on a vast ecosystem of third-party plugins and themes expose it to frequent vulnerabilities.  Many of these add-ons lack rigorous quality control and timely security updates, leaving sites open to exploitation.  Additionally, misconfigurations and poor maintenance practices further compound these risks.

Because of its ubiquity, hackers continuously invest effort in discovering new exploits for WordPress.  Even when the core software is updated, the weaknesses in ancillary components can be enough to compromise a site.  This creates an environment where maintaining security becomes a constant challenge, forcing organizations to invest heavily in monitoring and patching their systems.

Commitment to Security and Reliability: The Marketing.Legal Advantage

At Marketing.Legal and the Success.Legal professional ecosystem, we prioritize the security and integrity of our platforms.  We have consciously chosen not to use any WordPress code, nor do we rely on other open-source website platforms, plugins, or themes that frequently become targets of cyberattacks.  Instead, our proprietary web-application forms the cornerstone of our content management platforms, ensuring robustness and security for our users.  This strategic decision not only mitigates risk but also demonstrates our unwavering commitment to safeguarding client data and maintaining digital trust in an increasingly hostile cyber landscape.
