The Problems, Named Precisely
We have written about why companies leave Kentico at the business level. This post is the technical companion: the specific, recurring problems we find when Kentico sites land on our bench, explained plainly enough to check against your own installation. If several of these sound familiar, the platform is not failing you randomly. These are structural.
Problem One: Upgrades That Are Projects
Kentico's major version jumps have historically involved genuine architectural change, most famously the retirement of the old Portal Engine in favor of MVC development, which turned "upgrade" into "substantially rebuild" for sites built the old way. Even routine version moves need developer time, regression testing, and sometimes license spending. The practical result we see everywhere: installations frozen several versions back, because the upgrade is unaffordable this quarter, every quarter, while security support windows quietly close behind them.
Problem Two: The Developer Market
Kentico work requires .NET developers who also know Kentico's specific conventions, a small intersection that gets smaller outside major metros. Scarcity does what scarcity does: rates rise, timelines stretch, and businesses end up captive to whichever vendor built the site, because onboarding a second opinion is itself a project. Compare hiring for the platform on the other side of the Kentico vs. WordPress comparison, where the talent pool is the largest in web development.
Problem Three: The Ecosystem Gap
Need reviews, events, bookings, or a niche integration? On mass-market platforms that is a mature extension. On Kentico it is frequently custom development, budgeted and maintained by you, forever. The integrated marketing suite softens this for the features it covers, but the long tail of business needs lives outside the suite, and the long tail is where budgets go to be surprised.
Problem Four: The Editing Experience Tax
Marketing teams coming from consumer-grade editors find Kentico's authoring heavier: more structure, more clicks, more training, more requests routed through developers. Structure is genuinely valuable at enterprise scale. At typical mid-market scale it converts into a stale website, because the person with the update stopped making updates that require a ticket.
Problem Five: The Stack Bill
Windows hosting, SQL Server, licensing, and the specialized maintenance above stack into a carrying cost that exists before any improvement work begins, the arithmetic we walk through in the real cost of Kentico. The problem is not any single line. It is that the same money buys the mid-market business more outcomes elsewhere.
What to Do With a Diagnosis
Sometimes the answer is staying: a genuinely enterprise use case, a .NET shop, features actually in use. Then the fixes are operational: get current, get a second vendor capable of the platform, and budget upgrades as recurring reality. When the diagnosis says the platform outweighs the use case, the path is a planned migration, the discipline from our migration guide: content mapped, redirects preserved, SEO intact. Either way, the worst position is the frozen middle. Bring us your version number and your pain points, and we will tell you which conversation you are actually in. If it is the leaving one, our Kentico to WordPress migration service is the clean way out.
