How curta.solutions Compares: Presidio, Skyflow, Piiano, AWS Comprehend
Each comparison below is one specific axis with a citation. Where a competitor's current number cannot be verified from a public reference as of May 2026, the cell is marked UNVERIFIED. Do not take this page as a vendor decision document — take it as a starting point for your own scorecard.
vs Microsoft Presidio (open-source upstream)
Presidio is the open-source PII engine that several curta.solutions products are built on; the difference is what is wrapped around it.
| Axis | Microsoft Presidio | curta.solutions |
|---|---|---|
| Pricing. | Free, MIT licence (Ref: https://microsoft.github.io/presidio/). | Free tiers on all 13 products; paid tiers from €3/mo (see pricing). |
| Deployment model. | Self-hosted library + container; you operate it (Ref: https://microsoft.github.io/presidio/). | SaaS (ISO 27001 servers in Germany), Managed Private, Self-Managed (see anonymize.solutions). |
| Entity types out of the box. | ~20 built-in recognisers, extensible (Ref: https://microsoft.github.io/presidio/supported_entities/). | 50–390+ depending on product (see project pages: anonymize.dev 50+, anonymize.today 256, cloak.business 320+, anonym.life 390+). |
| Language coverage. | Depends on configured spaCy/transformers models; English first-class (Source: https://microsoft.github.io/presidio/analyzer/languages/). | 27–67 languages depending on product, RTL on anonym.legal and anonymize.solutions. |

vs Skyflow (US data privacy vault)
Skyflow positions as a managed data privacy vault for US enterprises; the comparison is about EU data residency, deployment model, and PII detection scope.
| Axis | Skyflow | curta.solutions |
|---|---|---|
| HQ / data residency. | US-headquartered; multi-region cloud presence advertised (Source: https://www.skyflow.com/data-privacy-vault as of 2026-05). | Germany; ISO 27001-certified German servers; EU-only residency by default. |

Frequently asked questions
Why didn't you compare against Privitar?
Privitar was acquired by Informatica in 2023; the product line continues under Informatica branding and a like-for-like comparison would require a current Informatica reference.
What about DataGuard or Eperi for DACH?
DataGuard sells privacy management governance (DPIA, GDPR documentation); Eperi sells cloud-data encryption; neither targets the same PII-anonymisation-for-AI use case as curta.solutions, so they are not in this comparison.
Why does curta.solutions emphasise MCP Server support?
Most curta tools ship with MCP Server endpoints so they can plug directly into Claude Desktop, Cursor, VS Code (Continue, Cline) and Windsurf without a custom integration; this is uncommon in the comparable vendor set as of May 2026.
