Comparison
HeaderHawk vs CentralCSP
CentralCSP is a CSP platform with a builder's bias. A policy builder, an evaluator, a scanner, CSP and SRI hash calculators and a Chrome extension sit alongside the reporting endpoint, with PCI DSS tooling on the paid tiers.
It is also the cheapest paid entry on this page — €4.99 a month — with 90-day retention on every plan. What that entry plan does not include is much volume: 15,000 reports a month, two applications, one user and no alerting.
So the comparison is not really about price. It is about whether you want tools that help you write a policy, or a reader for the reports the policy produces.

What CentralCSP does better
A comparison that finds no advantage anywhere is the one readers stop trusting. These are the things HeaderHawk does not do.
- Tools for building the policy
- A policy builder, an evaluator, a scanner, a CSP hash calculator, an SRI hash calculator and a Chrome extension. HeaderHawk publishes no policy tooling today, and does not author or grade policies.
- Retention is 90 days on every plan
- Including the €4.99 Starter. HeaderHawk's Free plan holds 15 days, Team 30, and Professional and Business 60 — so CentralCSP keeps a longer trail at every price on their table.
- Export, an API and SSO are on the plan table
- Data export, API access and single sign-on all appear as features in their plan comparison, and they publish API documentation. HeaderHawk has no export and no read API, and lists SSO as coming soon.
- PCI DSS tooling as a product surface
- PCI DSS tools are a named plan feature, with the script inventory framed around them and a published SAQ A document. HeaderHawk has a page explaining how its evidence maps to requirements 6.4.3 and 11.6.1 — and where it does not — but no dedicated compliance tooling.
- A very low entry price
- €4.99 a month is below HeaderHawk's cheapest paid tier, and buys a real plan rather than a trial. If two applications and 15,000 reports a month is your shape, it is the cheapest paid option on this page.
Where HeaderHawk is stronger
Each of these is something the product does today, not something on a roadmap.
- Free beats €4.99 for a small site
- HeaderHawk's Free plan carries 3 sites and 10,000 reports a month with no card. CentralCSP's Starter carries two applications and 15,000 reports for €4.99: more volume, fewer sites, and a payment method.
- Alerting is included where you would expect it
- CentralCSP's plan table lists 0 alerts a month on Starter and Advanced, with 500 starting on Pro at €79.99. HeaderHawk's alert rules — email, Slack or webhook, with a deduplication window and a daily or weekly digest — are part of the Team plan at $39.
- The drill-down is the point of the product
- Grouped violations that open onto the affected pages and the individual reports behind them, with the source file, line, column and the browser's script sample. That is what the product is organised around, rather than one tool among several.
- Noise held out of the alert path
- Extension URIs, data:, about: and blob: URLs, and bot user agents are classified as known noise, and a window containing nothing else raises no alert while staying visible in the dashboard.
Which one to pick
Pick CentralCSP if…
- You want help writing the policy as well as reading the reports. The builder, evaluator, scanner and hash calculators are a genuinely different offer.
- 90 days of retention at a low price is the requirement, or you need data export, an API or SSO — HeaderHawk has none of the three.
- Their PCI DSS tooling maps to how your assessor wants the evidence presented.
Try HeaderHawk if…
- You want to start at zero, or you want alerting without reaching their third tier.
- The daily work is triaging violations rather than authoring policy, and you would rather have one screen that does that well than a suite of tools around it.
HeaderHawk has no data export, no API for reading your data, no HTTP response-header monitoring, no configurable alert thresholds and no spike detection. If any of those is a requirement, the comparison above is already decided.
Other comparisons
- HeaderHawk vs Report URIThe incumbent, now sold as a client-side security platform. Far more product; a much higher floor.
- HeaderHawk vs URIportsThe closest on price and the broadest in scope. CSP is one of many report types for them, and the whole product here.
- HeaderHawk vs CsperThe other developer-first CSP tool. It writes and grades policies; this one reads reports. Two small products, honestly compared.
- HeaderHawk vs building it yourselfThe real default: a Lambda writing to S3. The endpoint is an afternoon; everything after it is the product.
