OneTrust vs Ketch: Pricing, DSAR Automation and Which One to Buy

Short answer: Ketch is the only one of the two that publishes a price you can read without a sales call, starting free and running to $499 a month. OneTrust publishes nothing and carries a reported platform minimum near $10,000 a year. That makes Ketch look like the budget option, and for a small consent deployment it genuinely is. The surprise sits in the procurement data: the reported median Ketch contract is about $35,000 a year against OneTrust's $11,970, roughly 2.9 times higher. Both numbers are real and both are misleading on their own, for reasons worth understanding before either goes in a budget.

The reason this matters for anyone shopping subject request handling: neither vendor sells DSAR automation at a price it prints. Ketch treats rights workflows as a paid add-on at Plus and bundles them only at custom-quoted Pro. OneTrust puts its Privacy Rights Automation module behind the platform minimum. Everything below is published list pricing and aggregated buyer-reported procurement data read in September 2026, not quotes.

OneTrust vs Ketch at a glance

Is Ketch cheaper than OneTrust?

At the entry point, yes, decisively. Ketch has a free tier covering up to 5,000 monthly unique users and a Starter plan at $150 a month for up to 30,000. OneTrust has no published price and a reported minimum around $10,000 a year, so the cheapest readable Ketch plan is roughly a twentieth of the cheapest OneTrust conversation.

At the median, the ranking flips. Reported procurement data puts the typical tracked Ketch contract near $35,000 a year and the typical tracked OneTrust contract near $11,970. That is a 2.9x inversion of the positioning both companies market, and it catches buyers out.

Two things explain it, and neither is a vendor doing anything underhanded. The first is a sampling artifact. Ketch's small customers buy self-serve with a credit card at $150 a month and never appear in procurement data at all, because nothing was negotiated and no contract was tracked. The buyers who do show up are the ones large enough to run a purchasing process, which means they are on Pro. The Ketch median is measuring Pro, not Ketch. The second is that OneTrust sells dozens of separately priced modules, so a large share of its tracked contracts are one company buying one cheap module, most often cookie consent. Its median is measuring the market's most common small OneTrust purchase, not a privacy program.

There is a third point that gets missed, and it is the one to carry into any vendor evaluation. The Ketch median rests on 7 unique buyers. OneTrust's rests on 153. Ketch's middle half looks tight, running about $17,894 to $45,000, and it is tempting to read that as evidence the vendor quotes consistently. It is not. Low variance across seven buyers means seven companies happened to look similar to each other. Only the OneTrust sample is large enough to behave like a market price. Always read a median next to its buyer count, and treat anything under about 30 buyers as an anecdote with a decimal point.

What is the difference between OneTrust and Ketch?

Architecture, and it drives everything else. OneTrust is a governance suite. It records that a decision was made, routes it to the right owner, and produces the audit trail. Its catalog spans consent, subject rights, assessments and PIAs, data mapping, third-party risk, incident response, policy management and AI governance, each priced on its own.

Ketch is a data permissioning platform. Its bet is that capturing a consent choice is the easy half, and the valuable half is enforcing that choice programmatically in the systems downstream: suppressing a user in the CDP, stopping a tag from firing, propagating a deletion into the warehouse. That is genuinely different work, and it is why Ketch appeals to engineering-led teams and OneTrust appeals to legal and compliance-led ones.

The practical consequence is who has to own the tool. OneTrust is configured by a privacy team and can run without engineering involvement past the initial integration. Ketch pays off in proportion to how deeply you wire it into your stack, which means it needs engineering time you have to actually budget. Buying Ketch and using it as a banner is paying for the expensive half and using the cheap half.

Does Ketch do DSARs, and how does it compare to OneTrust?

Both do, and on this specific module the capability gap is narrower than the price gap suggests. The real difference is how you buy it, and in both cases the answer is that you cannot buy it cheaply.

Ketch's published ladder is a consent ladder. Free and Starter do not include rights workflows at all. Plus, from $499 a month billed annually, treats them as a paid add-on. Full DSR automation alongside data mapping, risk assessments and marketing preference management arrives only at Pro, which is custom quoted for organizations above 100,000 monthly unique users. So the entire readable price list buys consent, and the thing you came for sits above it.

OneTrust reaches the same outcome by a different route. Privacy Rights Automation is reported near $275 a month list, which sounds approachable until you notice you cannot buy $275 a month of OneTrust. The reported platform minimum is around $10,000 a year, so the module costs about a third of the floor you have to clear before you are allowed to buy it.

This is a pattern rather than a coincidence. Across this category the published number is a consent price and the DSAR price is a conversation, and the same structure shows up in our Osano pricing and Ketch pricing breakdowns. If subject request fulfillment is the actual job, both of these vendors are selling you a consent platform with your requirement attached to the top of it. Our OneTrust DSAR page covers what that module does and does not do in practice, and where a focused tool is the cheaper answer.

Ketch published pricing, tier by tier

The gap between that table and the procurement data is the single most useful fact on this page. The published ladder tops out at $499 a month, which is $5,988 a year. The reported median tracked contract is about $35,000. The typical negotiated Ketch buyer is paying roughly six times the highest price Ketch prints, because they are on Pro and Pro is where the meters live: monthly unique users as the headline, then properties and brands, the number of downstream systems permissions push into, and which of the five separately priced modules are switched on.

Where OneTrust genuinely wins

Catalog depth. If privacy has to sit alongside third-party risk, incident response, policy management and assessments under one vendor with one audit trail, no competitor matches the module count. That consolidation is the product.

Jurisdictional coverage. A company operating across the EU, the UK, Brazil, Canada and twenty US states needs configuration per regime rather than a US-and-EU default. OneTrust has the deepest coverage in the category and the largest partner ecosystem to configure it.

Procurement familiarity. It is the easy internal approval, and 153 tracked buyers against Ketch's 7 is not only a data point about pricing. It tells you how many peers your risk committee can call. Reported negotiation outcomes average about 20 percent off the initial quote, so the sticker is not the price.

Where Ketch genuinely wins

You can start today. A free tier that does not expire and a $150 plan you can buy with a card are real advantages in a category where almost everything begins with a demo request. If your requirement is a compliant banner on one property, Ketch is finished before a OneTrust scoping call is scheduled.

Enforcement downstream of the banner. Most consent tools capture a preference and leave honoring it to whoever owns the CDP. Ketch propagates the decision into connected systems. If your exposure is marketing tags and audience syncs continuing to fire for people who opted out, that is the specific problem Ketch was built for.

Fit for engineering-led teams. API-first, developer-friendly, and configured in code rather than in a console. Teams that already treat infrastructure as code will find it faster to live than a suite.

One honest caveat on both. Consent and permissioning tooling tells you what a user allowed. It does not tell you where that user's data actually ended up. If your warehouse has tables nobody registered and pipelines nobody can vouch for, that gap is upstream of privacy, and monitoring freshness, schema drift and silent pipeline failures is a different discipline from consent. Buying a privacy platform will not close it.

Which one should you buy?

Match the buy to the obligation you actually carry.

Buy OneTrust if you are consolidating several compliance functions under one vendor, you operate across many jurisdictions, and a five-figure floor is normal for your budget. You are buying breadth and institutional comfort, and both are real.

Buy Ketch if consent enforcement across a modern marketing and data stack is the problem, you have engineering capacity to wire it in, and you want to start small and provably. Read the free tier as a genuine trial, not a lead magnet.

Buy neither if the honest description of your requirement is that you receive a handful of access, deletion and correction requests a month and the painful part is finding every place one person's data lives before the clock runs out. That is a fulfillment problem, not a consent problem, and both vendors price it above their published tiers. A focused tool that does DSAR automation handles the same statutory obligation without a consent platform attached. Before you shortlist anyone, confirm which state privacy laws apply to your business, because the answer often narrows the requirement more than any feature grid will.

Frequently asked questions

How much does Ketch cost?

Ketch publishes a free tier at $0 for up to 5,000 monthly unique users, Starter at $150 a month for up to 30,000, and Plus from $499 a month billed annually for up to 100,000. Pro is custom quoted above that. Reported procurement data puts the median tracked contract near $35,000 a year across 21 purchases by 7 unique buyers, with recorded deals from about $5,455 to $52,000. The full tier breakdown sits in our Ketch pricing guide.

Is Ketch a good OneTrust alternative?

For consent management, yes, and it is the strongest one if enforcement in downstream systems matters to you. For replacing OneTrust as a whole, no. Ketch does not carry the assessment, vendor risk, incident response and policy modules that companies buy OneTrust to consolidate. We keep an honest side-by-side on the Ketch alternative page, and a wider view of the field on OneTrust competitors.

Why is Ketch's median contract higher than OneTrust's if Ketch is the cheaper option?

Because the two medians measure different purchases. Ketch's small customers buy self-serve and are never tracked, so its sample is entirely larger Pro buyers. OneTrust sells dozens of cheap standalone modules that are tracked, which pulls its median down. Neither figure is the price of a comparable privacy program, and Ketch's rests on only 7 buyers.

Does Ketch replace OneTrust for DSARs?

It can, at the right tier. Ketch's DSR automation is bundled in Pro and available as a paid add-on at Plus, so it is a real capability rather than a checkbox. What it will not do is replace OneTrust's jurisdictional depth if you fulfill requests under many regimes at once. Cost-wise the two are closer than expected, since OneTrust's module sits behind a reported $10,000 minimum.

Which is better for a small privacy team?

Ketch, on price and time to value, provided your requirement is consent. Its free and $150 tiers are buyable without a procurement cycle, while OneTrust's reported floor plus implementation at 20 to 40 percent of the subscription puts year one well into five figures. If the requirement is request fulfillment rather than consent, neither is sized for a small team and a dedicated tool costs less than either add-on.

What are the best alternatives to both?

Depends on the module. For consent, Osano and Cookiebot are the usual shortlist, with Osano the cheapest established platform at a reported median near $8,459. For a full privacy platform, DataGrail and TrustArc are the closest like-for-like at reported medians near $50,000 and $15,120. For subject request fulfillment on its own, a focused tool beats a suite on both cost and setup time. Our OneTrust alternative page covers the field, including where OneTrust wins.
