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. Sifrsys uses a zero-retention AI API. Your documents are never used for AI model training. All AI processing is stateless and memoryless — data is processed in memory, answers are returned, and nothing is retained.

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.

The Problem

Clients call with questions your documents already answer.

Associates spend hours on calls that AI could resolve in seconds with a cited page reference.

Routine Questions

"What are the indemnification terms?" "When does the option expire?" Clients ask questions that are answered on page 14 of the agreement.

Email Chaos

Documents shared as email attachments. No version control, no access tracking, no audit trail of what was shared and when.

Client Isolation

Each client must only see their own documents. Generic file sharing tools don't enforce the kind of isolation law firms require.

How It Works

From document upload to client self-service.

Set up a branded client portal in minutes — not weeks.

Step 01

Create a branded portal for each client.

Set up a portal on your firm's subdomain with your logo and colors. Upload case documents and set permissions. Each client is completely isolated — Row-Level Security at the database level.

Client AI Q&A

What are the key indemnification terms in the merger agreement?

Indemnification is capped at 15% of aggregate consideration for general representations, with a $2.4M basket. Fundamental representations (title, authority, tax) survive 36 months with no cap.

Client sees only their authorized documents — other clients' files are invisible

Step 03

Know what your clients have read.

Stop wondering if your client reviewed the documents. Room Intelligence shows you exactly which pages they read, for how long, and when. Get alerts when critical documents go unread before deadlines. Notify clients via WhatsApp when new documents are uploaded — they tap and they're in.

Client Portal FAQ

Questions law firms ask about AI-powered client portals.

Clients access a branded portal on your firm's subdomain (e.g., portal.yourfirm.com). They can view case documents and ask AI questions about them. The AI retrieves answers only from documents the client is authorized to see, with exact page citations. This reduces routine calls — clients get instant answers instead of waiting for an associate.

Yes. Every portal runs on a custom subdomain with your firm's logo, colors, and branding. Clients see a professional interface under your domain — no Sifrsys branding visible unless you choose to show it.

The AI processes queries statelessly with zero data retention. No conversations, documents, or query history is stored or used for training. Row-Level Security ensures each client sees only their own documents. The AI cannot access other clients' materials even if they're in the same firm account.

Clients receive a passwordless magic link. One click and they're in — no account creation, no passwords. You control access duration, download permissions, and watermarking. Revoke access at any time.

Any firm sharing documents with clients: corporate law firms (M&A, securities), litigation firms (discovery documents), IP firms (patent portfolios), real estate firms (transaction documents), and family offices. The AI Q&A feature reduces the volume of routine client questions by letting clients self-serve with cited answers.
