Sifrsys is an AI-native virtual data room and secure content intelligence platform. It is used for M&A due diligence, fundraising, board portals, investor relations, client portals, and any workflow requiring secure document sharing with AI-powered intelligence. Ask questions about your documents and get cited answers — the AI only retrieves from documents within each user's permission boundary.

Is my data used to train AI models?

No. Your documents, queries, and AI conversations are never used to train AI models — ours or our providers'. Conversation history is stored encrypted inside your own data room, governed by the same Row-Level Security as your documents.

What can I use Sifrsys for?

Sifrsys is used for M&A due diligence data rooms, startup fundraising, board portals and investor reporting, law firm client portals, VC deal flow management, legal discovery rooms, real estate transactions, and any scenario requiring secure document sharing with AI intelligence. The platform adapts to any use case involving sensitive documents and multiple stakeholders.

How is Sifrsys different from traditional virtual data rooms?

Traditional VDRs store and share documents securely but lack intelligence. Sifrsys adds permission-fenced AI document Q&A with cited answers, Room Intelligence AI deal advisor, page-level engagement analytics, and branded white-label portals on top of full VDR security features like 5-level permissions, dynamic watermarking, and tamper-proof audit trails. No per-page fees.

What security features does Sifrsys have?

Sifrsys includes AES-256 encryption at rest, TLS encryption in transit, row-level database security that enforces AI permission boundaries, hash-chained tamper-proof audit logs, two-factor authentication, 5-level granular permissions (none, fence, view, download, full), and dynamic watermarking on document views and downloads.

Can I use Sifrsys as a board portal?

Yes. Sifrsys works as a board portal with branded portals for each board, engagement analytics showing who read board materials, AI Q&A so board members can ask questions about documents, granular permissions to control what each member sees, and a complete audit trail for governance compliance. It is significantly more affordable than enterprise board portal software.

Does Sifrsys charge per page?

No. Sifrsys uses flat monthly pricing with no per-page fees, no per-user fees, and no overage charges. Plans start free (1 room, 100 MB, AI included) and scale to enterprise. Unlike legacy VDRs that charge $0.50–2.00 per page, Sifrsys pricing is predictable.

How quickly can I set up a data room?

You can create a data room and start uploading documents within minutes. Documents are automatically parsed and indexed for AI retrieval. Invite participants with passwordless magic link access — they click a link and are in immediately. No sales call required to get started.

Can I use Sifrsys for fundraising?

Yes. Startups use Sifrsys data rooms to share pitch decks, financials, and legal documents with investors. Engagement analytics show which investors are most engaged with your materials. Permission groups let you share different materials with different investor tiers. AI Q&A helps investors find answers without back-and-forth emails.

What is Room Intelligence?

Room Intelligence is an AI deal advisor built into every data room. It tracks who viewed what documents and for how long, identifies which contacts at which organizations are most engaged, detects when parties go cold, and generates automatic engagement alerts. You can ask it natural-language questions like 'Which buyer group is most engaged this week?' and get data-backed answers.

Can I use Sifrsys as a client portal for my law firm?

Yes. Law firms use Sifrsys as a branded client portal. Clients can ask AI questions about their case documents and get cited answers, reducing routine calls. The portal appears under your firm's brand with custom subdomain, logo, and colors. The audit trail and watermarking meet compliance requirements, and granular permissions control what each client sees.

Intralinks Alternative

The original data room, or the modern one.

Intralinks pioneered the VDR in 1996 — and its reviewers still describe a dated interface and complicated, quote-based pricing. Sifrsys is the modern alternative: self-serve in minutes, flat published plans, and permission-fenced AI chat with clickable citations in every plan.

Why Teams Look Beyond Intralinks

Three reasons deal teams evaluate alternatives.

Intralinks earned its place as the industry pioneer — and these are the gaps its own reviewers point to.

Opaque, Unpredictable Pricing

There's no public price list — quotes come through sales negotiation. Reviewers describe a "complicated pricing structure," "hidden costs such as cost per media," and a variable fee structure that can leave a significant gap between initial budget and final invoice.

A Dated, Clunky Interface

Reviewers call the interface "dated, complicated and clunky," cite a steep learning curve and rigid customization, and note the mobile experience "could be smoother." Legacy architecture shows its age next to modern tools.

AI Bolted On, Decades Later

DealCentre AI launched in 2025 — nearly three decades after the platform itself. Its Ask Link assistant offers limited citation tracking, and the retrieval architecture behind it isn't publicly disclosed.

Intralinks Alternative FAQ

Questions teams ask when comparing.

Sifrsys is a strong Intralinks alternative if a modern interface and predictable pricing matter to your deal. Intralinks pioneered the virtual data room in 1996 and is deeply trusted by large enterprises and investment banks, but reviewers describe its interface as dated and its pricing as complicated. Sifrsys is AI-native and self-serve: sign up in minutes, upload documents, and ask questions in natural language with answers cited to the exact page or spreadsheet cell — included in every plan.

Intralinks pricing is quote-based with no public price list. As of mid-2026, reported figures start around $25 per user per month on annual contracts for creators, enterprise contracts typically start at $10,000+ annually, and large implementations can exceed $720,000 per year — with reviewers citing hidden costs such as per-media fees and variable fee structures that cause gaps between initial budget and final invoice.

Intralinks has a 25+ year track record, is trusted by 99% of Fortune 1000 companies, has facilitated over $35 trillion in transactions across 10,000+ M&A deals annually, offers 24/7 expert support, and holds enterprise security certifications including ISO 27001 and SOC 2. Sifrsys is a newer product still building its market track record and does not yet hold those certifications. If a decades-long enterprise pedigree is your priority, Intralinks is a credible choice — we'd rather tell you that than pretend otherwise.

Yes — Intralinks launched DealCentre AI in 2025, including the Ask Link conversational assistant, AI redaction, and document summarization. However, its citation tracking is limited and its retrieval architecture is not publicly disclosed. Sifrsys was built AI-native from day one: every answer carries clickable citations to the exact page or spreadsheet cell, and AI retrieval is bounded by each participant's permissions at the database level.

Data rooms are typically set up per deal, so most teams switch by starting their next deal on Sifrsys rather than migrating an active one. There's no sales negotiation or implementation project: sign up self-serve, upload your documents (PDF, DOCX, XLSX, PPTX), and they're parsed and AI-indexed automatically. Participants get passwordless magic-link access — no training required. The Starter plan is free, so you can evaluate with a real document set before committing.

Try the Difference

No quote. No negotiation. No training.

Skip the sales cycle: sign up self-serve, upload a real document set on the free plan, and see permission-fenced AI with clickable citations in minutes — the comparison that matters most takes five minutes to run yourself. And before you upload a single document, the Trust Center states our security posture plainly, including what we do not yet claim.
