Is Cloudflare Pro Worth It?

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 than ordinary policies based on IP/CIDR, Path, and Header, and can even introduce the risk of false positives. Therefore, I don’t believe that individuals or small teams truly need to write regax to match complex attack patterns.

User Agent Blocking

User Agent Blocking allows users to configure actions such as Block and Challenge for specific User-Agent request headers. Its scope is the entire domain rather than an individual subdomain. In terms of quota, Pro increases the limit from 10 rules on Free to 50. However, it is worth mentioning that Cloudflare’s official documentation now explicitly recommends using http.user_agent in Custom Rules to achieve the same result. Therefore, in my opinion, User Agent Blocking looks more like a legacy or backward compatibility feature that has not yet been officially retired.

Zone Lockdown

Zone Lockdown allows IP/CIDR based allowlists to be configured for specific domains, subdomains, and URLs. This capability likewise has a quota of zero on Free, while Pro allows 3 rules. However, just like User Agent Blocking, Cloudflare also recommends using Custom Rules to create an equivalent IP/CIDR allowlist. Therefore, I consider Zone Lockdown another kind of legacy or backward compatibility feature that has not yet been officially retired. Of course, Cloudflare has not announced any specific deprecation plan, and the legacy characterization is merely my own analysis. It remains one of the capabilities available starting with Pro.

Super Bot Fight Mode

Super Bot Fight Mode is an upgrade over Bot Fight Mode. Compared with the blanket verification provided by the basic Bot Fight Mode, which offers no granularity at all, Super Bot Fight Mode classifies traffic by bot type. More specifically, it gives Pro users several additional configuration options:

Different actions such as Allow, Challenge, and Block can be selected for Definitely Automated Traffic;
Different actions such as Allow and Block can be selected for Verified bots, including verified crawlers such as search engines;
Separate toggles are provided for JS Detections, Static Resource Protection, and Optimize for WordPress.

Since my WAF rules are already fairly detailed, the features provided here by Super Bot Fight Mode are not especially important to me.

Rate Limiting Rules

Rate Limiting Rules limit how many requests a client with the same characteristics can make within a given period. They are a fundamental way to prevent API abuse and brute-force attacks. The Free plan provides only 1 rule, fixes the counting period at 10 seconds, and allows matching only on Path and Verified Bot. Pro raises the quota to 2 rules, extends the counting period to as long as 1 minute, and additionally unlocks fields including Host, URI, Full URI, and Query. Note that custom counting expressions and more detailed fields such as Method, Source IP, and User Agent require Business. Furthermore, although the increase from 1 rule to 2 on Pro may not look like much of an upgrade, my personal experience suggests that the second rule is effectively an independent slot for the Leaked Credentials Detection mentioned earlier. Protection for the service or API itself can then be handled entirely by the other rate limiting rule.

Performance Improvements

Cache Rules

Cache Rules define caching behavior for particular types of requests, such as whether they should be cached, for how long, and at which cache tier. This feature is also available on Free, but the Pro plan raises the quota from 10 rules to 25. In my experience, Cache Rules are genuinely useful. For projects that I don’t wanna modify directly, or websites with a slightly more complex structure that need different caching policies by path or file type, the 10 rules offered by Free can run out very quickly. Therefore, this feature is essential to me.

Image Optimization

Polish is another feature I rather like, and it is likewise completely unavailable to Free users. Under Speed - Settings - Image Optimization, you can configure the Polish level and choose no compression, lossless compression, or lossy compression. Of course, I recommend using Configuration Rules to apply different Polish strategies to different subdomains.

Redirects

Redirects is divided into Single Redirects and Bulk Redirects. Both are actually available on Free, but the Pro plan raises the Single Redirects quota from 10 to 25 and the total number of Bulk Redirects from 10,000 to 25,000. Before these features were available, I even wrote a set of Workers specifically to handle various redirect rules. In my experience, the Free quota is basically enough if you only need a few scattered redirects. However, if you have migrated an entire website or merged domains and need to import mappings in bulk, the 25,000 entry quota on Pro gives you considerably more room.

Automatic Platform Optimization

Automatic Platform Optimization is an acceleration solution created specifically for WordPress websites. I have never been fond of WordPress, so I will not go into detail here. However, it is worth mentioning that this feature costs an additional USD 5 per month on Free but is included directly with Pro. If you are a WordPress user, I suppose this counts as saving a subscription fee?

Additional Features

Custom Error Pages

Custom Errors primarily replaces Cloudflare’s default branded challenge and error pages with your own custom pages. The coverage is very comprehensive: everything from 4xx and 5xx errors to WAF blocks and challenges can be customized. This capability also starts with Pro. On the Free plan, visitors will always see the default pages. In addition, it allows users to upload pages in advance as Custom Error Assets stored in the CDN cache, then reference them from multiple Custom Error Rules without repeatedly inlining the same page in every rule. I wrote a Worker that uses wrangler.jsonc and Gitea Actions to configure, deploy, and update these pages automatically, which makes maintenance very convenient.

Health Checks

Health Checks actively probe origins. You can specify the path, response code range, probe interval, and other details, then receive a notification almost in real time once an origin becomes unhealthy. Free allows zero Health Checks, while Pro provides a quota of 10. The accompanying Health Checks Analytics also provides detailed analysis and monitoring of origin availability, latency, and failure reasons. This capability has now been integrated into the larger Smart Shield suite, although the standalone configuration entry still exists. Ten checks for Pro users is neither especially generous nor particularly stingy. For personal infrastructure or the core services of a small team, I think it is entirely sufficient. Of course, I would still like Cloudflare to provide Pro users with a larger quota so that more services can be covered comprehensively.

Web Analytics

Web Analytics itself is actually a free product available regardless of plan. Add a JavaScript snippet and you receive privacy friendly, cookie free visitor analytics. Free users can use it too, but its rules feature is what the plan limits. Free allows zero Web Analytics rules, meaning the analytics script can only be injected uniformly across the entire website and all its subdomains. The Pro plan provides 5 rules, allowing precise control over script injection by subdomain.

Privacy-first HTTP Traffic Analytics

HTTP Traffic Analytics and Web Analytics above are two completely different products, although users often confuse them. HTTP Traffic under Zone Analytics doesn’t rely on JavaScript at all and is based entirely on Cloudflare’s CDN logs. The Free plan only shows a simplified Web Traffic dashboard with three metrics, Requests, Bandwidth, and Unique Visitors, as well as a map of requests by region. Pro fully unlocks filtering across every dimension. Since it doesn’t depend on front-end script injection, I actually use this analytics system more often than Web Analytics. There is no need to worry about browser extensions blocking the script and causing missing statistics, and its data also reflects the requests actually processed on the server side more accurately.

Snippets

Snippets are lightweight JavaScript programs that run on Cloudflare’s edge network and can perform special transformations on requests and responses. They cover cases that are more complex than Transform Rules but not substantial enough to deserve a separate Worker, such as Geo-based Rewrites. This feature is completely unavailable on Free and is unlocked starting with Pro, which provides a quota of 25 Snippets with 2 subrequests allowed for each one. Since execution time is limited to 5ms, memory usage to 2MB, and the bundle size to no more than 32KB, Snippets are unsuitable for complex logic. As mentioned earlier, however, they are entirely sufficient for those intermediate cases such as special request rewrites, and they cost nothing extra.

Analytics Retention

This is actually more complicated than one might imagine. Cache Analytics is completely unavailable on the Free plan. Starting with Pro, users can view data retained for 7 days. However, for WAF related analytics such as Security Events, Free and Pro are actually identical: Security Events are retained for 24 hours and Security Analytics for 7 days. Only Business increases these periods to 3 days and 31 days respectively. In other words, when it comes to security analytics, the only substantive difference between Pro and Free is that Security Events supports Print Report. The retention period itself doesn’t increase. Therefore, if you are hoping to see a longer history of security logs by upgrading to Pro, you will probably be disappointed.

Others

Ticket Support

According to Contacting Cloudflare Support, Free users can’t open Support Cases at all. Starting with Pro, users finally gain the right to submit tickets to Cloudflare, although Chat and Emergency Phone Call still require Business and Enterprise respectively. By the way, Cloudflare processes support tickets in the order of Premium Enterprise, Standard Enterprise, Business, and Pro. Therefore, while Pro users can open tickets, their priority remains at the bottom of the queue. Even so, ticket support isn’t an exceptionally strong selling point to me, but going from no official support channel at all to being able to open a case and have someone follow up is still a reassuring step from zero to one.

What Does Pro Not Include?

Finally, I would like to discuss what Pro does NOT include and list a few common misconceptions so that expectations are not raised too high in advance.

I will not repeat the limitations already mentioned above, such as regax matching in Custom Rules, custom counting expressions in Rate Limiting Rules, or Live Chat and Emergency Phone Call support.

What I find rather strange is that many people assume Advanced Certificate Manager is a Pro feature. In reality, features such as custom certificates are paid add-ons on every plan. Pro users need to purchase it separately just like Free users, and the same is true even for Business and Enterprise.

From my perspective, Load Balancing and its pricing model are probably among the features I understand the least. Like Advanced Certificate Manager above, Load Balancing is also a paid add-on on every plan. This creates a subtle disconnect from the Health Checks discussed earlier. Pro already includes a quota of 10 Health Checks that can actively detect origin failures and provide nearly realtime alerts. Yet once a failure is detected, automatically moving traffic to a backup origin for actual failover requires paying separately for Load Balancing. In other words, the discovering the problem part is already covered, but solving the problem still costs extra. In my view, these are two continuous steps serving the same ultimate goal, so charging for them separately leaves the product feeling somewhat incomplete.

Client Side Security evolved from Page Shield. Both Free and Pro only provide basic Script Monitoring. The more advanced Connection Monitoring, Cookie Monitoring, and Page Attribution all require Business. If third-party script supply-chain security is your reason for upgrading to Pro, you are bound to be disappointed. This is also another pricing decision that I don’t understand, and it puzzles me even more than Load Balancing. I can understand charging extra for continuous behavioral analysis capabilities such as malicious script detection, malicious connection detection, and code change detection. However, Content Security Rules, which are also placed inside the Client-Side Security Advanced add-on, are essentially just rule matching and blocking logic. Their technical form is almost identical to the Custom Rules already included with Pro. The advanced fields in Cookie Monitoring ultimately expose only a few more fields that have already been collected, without creating any meaningful additional compute cost. In other words, at least part of this add-on looks less like an attempt to cover actual costs and more like a deliberate gate for product segmentation. Not every capability separated into the add-on has a sufficiently convincing reason to be there.

It’s true that the Health Checks mentioned earlier have now been incorporated into the Smart Shield suite, but Smart Shield itself actually has three tiers. The basic Smart Shield contains only Smart Tiered Cache and Connection Reuse and is available to Pro, Business, and Enterprise alike. However, Argo Smart Routing, the feature that actually reduces cross region latency and dynamically selects routes based on real-time network conditions, is a separately purchased, usage based service for both Pro and Business. Only Enterprise customers can preview it for free as a non-contract service. I understand that Argo Smart Routing continuously consumes compute and network resources, so its marginal cost is not as low as that of quota-based features. However, this should be the most cost effective acceleration capability for cross-region traffic, yet neither Pro nor Business receives it. That genuinely makes me question the commercial prospects of this pricing strategy.

Conclusion

After looking at the entire package, whether Pro is worth it will naturally have a different answer for every reader. For individuals with a fair amount of infrastructure or small teams, Pro is absolutely a good choice. On the other hand, if all you run is a personal blog or a low traffic website, Free together with Custom Rules can already cover most scenarios. In my view, Pro is more about bringing fundamental capabilities that are entirely absent or given painfully small quotas on Free up to a normal level, rather than bringing advanced capabilities down to a cheaper plan. Whether it is worth the money depends entirely on how strongly your own needs call for the improvements above.
