RedactProof vs CaseGuard Studio: Browser-Based vs On-Premise Redaction

General informational purposes only - not legal advice. Pricing and feature claims verified May 2026 from caseguard.com. Verify current details on the competitor's website.

CaseGuard Studio handles a lot. Video, audio, images, documents - all redacted from a single desktop application, all processed on your machine, all without files touching a cloud server. For law enforcement agencies and government bodies managing body-cam footage alongside evidence documents, that breadth matters.

But a redaction platform built around video is a different product to one built around documents. If your team handles PDFs, Word files, or scanned records - and video is not part of the picture - the comparison shifts. CaseGuard Studio runs only on Windows, requires installation and hardware investment, and its pricing is not publicly listed. RedactProof runs in any browser, requires nothing to install, and starts free.

This comparison covers both products honestly. CaseGuard is the better fit for some organisations. RedactProof is the better fit for others. The differences are concrete enough that the right choice should be clear by the end.

What CaseGuard Studio is and how it works

CaseGuard Studio (at the time of writing, May 2026) is an on-premise desktop application for Windows 10 and Windows 11. It does not run natively on macOS or Linux - if you use a Mac or Linux machine, you would need a Windows virtual machine to operate it.

Installation is required. After purchasing a subscription, you receive a download link by email and install the software locally. Files are processed on your hardware and never leave your network - which is a genuine privacy advantage for sensitive operational data.

The platform supports 750+ file types and handles:

• Video redaction - faces, licence plates, screens, objects in body-cam and CCTV footage
• Audio redaction - spoken names, addresses, and identifiers, with transcription and translation in 100+ languages
• Document and image redaction - PDFs, scanned records, email exports
• Automated PII/PHI detection across 33+ categories

CaseGuard's primary user base is law enforcement, government agencies, and legal teams managing evidence files where video and audio are as common as paper documents. The platform was built for that mixed-format, high-volume operational context.

Where CaseGuard has the edge

Be direct: CaseGuard is better than RedactProof in specific situations.

Multi-format redaction in one tool

If your workflow combines video, audio, and documents - say, a FOIA response that includes body-cam footage, recorded interviews, and written reports - CaseGuard handles all of it from one interface. RedactProof does not process video or audio at all. That's not a limitation we're planning to close. Document redaction done well is the focus.

Windows-native performance for high-volume media

Processing 4K video footage or bulk-transcribing hours of audio is computationally intensive. Running that workload on local hardware with a native Windows application - with GPU acceleration available - will outperform any browser-based tool for that use case.

On-premise for operationally sensitive files

CaseGuard processes everything locally with no internet requirement. For agencies with strict network controls around operational data - active investigations, classified material - that offline capability matters. RedactProof's standard detection engine also runs locally in the browser, but the Precision Engine sends extracted text (not the document) to Cloudflare Workers AI for enhanced PII detection. If your network policies require fully air-gapped processing, CaseGuard's local-only architecture is the stronger choice.

Where RedactProof has the edge

No installation, no IT ticket

RedactProof runs in any modern browser. There is nothing to install, no system requirements to meet, no admin rights needed. A paralegal can start redacting a SAR response on their existing laptop without involving IT. For most document-focused teams, that matters more than having video support they will never use.

CaseGuard requires Windows 10 or 11, a minimum 16 GB RAM, 100 GB storage, and a dedicated GPU is recommended for video work. That's a reasonable spec for a media workstation - but if you just need to redact PDFs, it's overhead that serves a purpose you don't have.

Simpler pricing, starting free

RedactProof's pricing is public and starts at free. The Core plan - which includes on-device AI detection, professional exports, and tamper-evident certificates - is £19/month. CaseGuard does not publicly list prices for any of its plans. You request a quote or speak to their team. For a small law firm or HR department trying to assess cost before committing, that's a meaningful friction point.

Tamper-evident verification certificates

Every export from RedactProof's Core plan and above includes a verification certificate - a cryptographically signed record (Ed25519 signature) that the document was redacted and has not been modified since. This provides an auditable chain of custody for disclosed documents, which is useful for SAR responses, FOIA disclosures, and legal discovery. CaseGuard does not offer an equivalent verification certificate mechanism at the time of writing (May 2026).

For teams handling documents under data protection regulations such as GDPR, CCPA, or HIPAA, having that tamper-evident record is directly relevant to compliance workflows. Our guide on verification certificates covers how the signature scheme works and what it proves.

Works on any device

Windows-only is a real constraint. A solicitor reviewing documents on a MacBook, or a compliance officer who works across a Mac desktop and a Windows laptop, cannot run CaseGuard without a VM. RedactProof works on any operating system with a modern browser - Windows, macOS, Linux, even tablets for light review work.

Pricing

CaseGuard Studio does not publish prices on its website. The pricing page at caseguard.com/redaction-pricing/ (verified May 2026) lists four plan tiers - Doc Suite, Media Suite, Ultimate Suite, and Enterprise - but clicking through requires you to request a quote or speak to their sales team. This is typical for software aimed at government and law enforcement procurement, where contracts are negotiated and pricing varies by organisation size and requirements.

The first search result from CaseGuard's own site referenced plans starting at $99/month for AI redaction, but this could not be confirmed from the public pricing page at time of writing. Treat that figure as unverified - contact CaseGuard directly for a quote.

RedactProof pricing is public:

• Free - pattern-based detection, unlimited exports with attribution footnote
• Core - £19/month (or £190/year) - on-device AI detection, professional exports, tamper-evident certificates
• Pro - £79/month (or £790/year) - Precision Engine, unlimited documents, full audit trail
• Team - £249/month (or £2,490/year) - 5 seats, admin dashboard, custom outputs

For a team that only needs document redaction and can't justify contact-sales procurement, RedactProof's pricing model is a practical advantage.

Which is the better fit?

Choose CaseGuard Studio if your team redacts video or audio alongside documents, if you operate in a Windows-only environment, or if your compliance requirements demand fully air-gapped processing with no cloud dependency whatsoever. It's purpose-built for law enforcement and government agencies managing mixed-format evidence workflows.

Choose RedactProof if you process documents only, want to start immediately without installation, need public transparent pricing, or require tamper-evident verification certificates for compliance disclosures. The browser-based approach suits legal, HR, and compliance teams at law firms, healthcare providers, and professional services firms where document redaction is a specific task, not a multimedia workflow.
