Ongoing Security & Maintenance Of WordPress
The Most Frequently Hacked Website Platform In The World
WordPress is cheap. Open source software is free, and developers who handle WordPress are plentiful, and templates are mass-produced and sold by the hundreds on websites like Themeforest. This means there are more websites built on WordPress than any other platform, also making it the most hacked website platform in the world. The return-on-investment for a successful hack is much higher as there are more targets available.
WordPress needs to be constantly updated with security patches (by web developers who have nothing to do with real estate), and plugins need to stay compatible with the core upgrades. Also, insecure plugins are vulnerable to hacks, and also need constant updates.
The maintenance of WordPress sites requires a lot of high-level tech hands on deck with unpredictable frequency of updates, and this often cancels out the cost savings during the setup phase with more premium solutions such as Brixwork.
