Is Cloudflare Pro Worth It?

2026.08.19

2026.08.20

In the blink of an eye, I have been a Cloudflare user for nearly ten years, long enough to watch both the company and its stock price grow dramatically. However, today I’m not planning to introduce any specific Cloudflare product or feature. In my opinion, Cloudflare’s technical documentation is among the most detailed and clearest in the industry, and Cloudflare also does a great job of building anticipation for every new product through Discord and the Cloudflare Blog. This is also why I rarely write articles about specific Cloudflare products. It’s not because I don’t use them, but because you can find almost all the information you need in the official documentation. Recently, several readers who are also long time Cloudflare users happened to ask me what Cloudflare Pro offers and whether it is worth. That led to this article, in which I would like to discuss whether Cloudflare Pro is merely a subscription for the faithful when it comes to individuals and small teams.

Preface

Although it is hardly necessary, I still want to make one thing clear: This article is not sponsored by or affiliated with Cloudflare. I paid for the subscription myself, received no compensation or other benefits from Cloudflare, and am writing purely from my personal perspective as a user.

To answer whether Pro is worth it, we naturally need to understand which features Cloudflare provides to Pro users. While organizing the material myself, I also tried asking Claude and Gemini for help, but I quickly found too many omissions in their answers. They didn’t even mention some Pro features that I consider essential. That is precisely why I believe this article is necessary. Since there is quite a lot to cover, let’s discuss it by category.

Network Security

Full Managed Ruleset

First comes Managed Rules, an upgrade that is automatically enabled once you become a Pro user. It contains a comprehensive WAF ruleset maintained by Cloudflare and updated very frequently. Judging from the WAF Changelog, new detection rules are released almost every week, and sometimes even more frequently. Its response to newly disclosed CVEs is also quite fast. For example, an update this April added corresponding rules for vulnerabilities disclosed in the same month, including Cisco Secure FMC (CVE-2026-20079) and FortiClient EMS (CVE-2026-21643). Compared with this full ruleset for Pro users, the basic version for Free users is nowhere near it in either update frequency or coverage. They could almost be considered two different products. Therefore, this is also the Pro feature I personally value the most. At least from my perspective, I’m absolutely willing to pay for a frequently updated security ruleset with ongoing expert support.

OWASP Core Ruleset

OWASP Core Ruleset is likewise a feature that requires no additional action and becomes available automatically once you subscribe to Pro. It’s an industry standard, general purpose Web application protection ruleset containing rules against classic attacks such as SQL injection and XSS. Unlike Managed Rules, where Free users still receive some basic protection, the OWASP Core Ruleset starts with the Pro plan and is completely unavailable to Free users.

Leaked Credentials Detection

Leaked Credentials Detection checks whether the username and password in a login request have appeared in known data breaches. It is one of the capabilities enabled by default even on Free, but Free users only receive the cf.waf.credential_check.password_leaked field. Starting with Pro, the additional cf.waf.credential_check.username_and_password_leaked field is unlocked, allowing the username and password combination to be checked more precisely. In other words, Free plan doesn’t offer the same level of detection granularity and may mistakenly affect users who have used a weak password but whose account itself has never appeared in a credential stuffing dataset. Pro can significantly reduce the possibility of such false positives. If your service includes a website with a login endpoint, I consider this a low cost but genuinely useful improvement.

Custom Rules

Custom Rules is the most fundamental and flexible WAF capability. Cloudflare lets users match conditions such as IP/CIDR, ASN, UA, Path, and Header, then apply different actions. I believe this is also the capability most familiar to Cloudflare users. In terms of quota, Pro raises the limit from 5 rules on Free to 20. That is more than enough for personal infrastructure or the core services of a small team. It is worth mentioning, however, that regular expression matching requires Business and is unavailable even on Pro. In my own experience, regular expressions are not particularly suitable for individuals or small teams anyway. Poorly written regex rules can be much less effective...
