The New Standard

AI is transforming deal execution. Here's what it takes to do it right.

Three non-negotiables for AI in confidential workflows.

01

Data isolation

Documents never leave your tenant. Retrieval is fenced by Row-Level Security at the database layer — not application code.

02

Zero training

Your documents, queries, and answers are never used to train any AI model — ours or our providers'.

03

Verified answers

Every response cites the exact page or cell it came from. No fabricated clauses, no invented figures.

Sifrsys delivers all three.

Pillar 01

AI that sees only what you're allowed to see.

Every AI query is fenced by Row-Level Security at the database level. When a participant asks a question, the AI retrieves only from documents within their permission boundary. It cannot see, reference, or learn from anything else.

  • Queries fenced by Row-Level Security — not application logic, database-level enforcement
  • Never used for model training — your data stays your data
  • AI conversations belong to you, not the platform
  • Your data is never used to train any model

Pillar 02

Every answer has a source. Every source is one click away.

Citations link to the exact page in a PDF or the exact cell range in a spreadsheet. Your participants don't trust the AI — they verify it. This isn't AI that's probably right. It's AI that shows its work.

  • Click a citation — jump to the exact page with the passage highlighted
  • Excel citations reference exact cell ranges (e.g. B4:B12)
  • Participants verify AI statements themselves — no trust required
  • 10-message conversational context for follow-up questions

Pillar 03

An advisor who has read every document and watched every participant.

Room Intelligence is not a dashboard. It's a deal advisor. It knows who looked at what, which contact at which buyer group is doing the heavy lifting, who's going cold, and what that means for deal velocity.

  • Knows who viewed what, when, and for how long
  • Identifies which contacts at which groups are most engaged
  • Detects when parties go cold and alerts you automatically
  • Ask natural-language questions about deal activity and get data-backed answers

Security

Your documents are protected at every layer.

Security is not a feature you configure. It is the foundation everything else is built on.

EncryptionAES-256 at rest. TLS 1.3 in transit. Every document, message, and file.
AI retrievalFenced by Row-Level Security — enforced in the database, not application code.
AI trainingDocuments, queries, and answers never train AI models. Conversation history stays encrypted inside your data room, under the same Row-Level Security.
Access control5 permission levels — none, fence, view, download, full — per document, folder, and group.
Audit logSHA-256 hash-chained over who, what, which resource, and when. Database trigger blocks updates. Exportable as CSV or JSON, integrity verifiable.
WatermarkingViewer name, email, timestamp, and IP stamped on views and downloads — policy set per room by admins.
SessionsConfigurable policies, idle timeouts, forced logout on policy change.

The audit chain, rendered

DOCUMENT_VIEWED

FILE_DOWNLOADED

PERMISSION_CHANGED

AI_QUERY

Each entry cryptographically references the one before it, covering the event's who, what, and when — and a database trigger blocks updates to audit records. Break one link and every hash after it fails: tampering is detectable.

Complete Platform

Every feature you need to run a deal.

A complete virtual data room with AI at its core. Not an AI wrapper — a full platform.

Cited answers across thousands of pages, linked to exact pages and cells.

09

Document Management

10

Authentication & SSO

Enterprise SSO, SMS-based 2FA, session management, configurable policies.

Programmable & Governed

Your data room, operable by AI — on your terms.

Connect the AI tools your team already uses to set up rooms, organize documents, and answer diligence questions — every action fenced by the permissions, policies, and audit trail you already trust.

01

Tools connect in — under your rules

AI tools connect into your data room through a permissioned interface — not by pasting files into a chatbot. Every read and action runs under the scopes and policies you set.

02

Only within permission

Automated access is fenced by the same Row-Level Security as your people. An agent sees exactly what its operator is allowed to — and nothing more.

03

Every action on the record

Each step is attributed to a named person in your hash-chained audit log, and sensitive actions wait for an admin's approval before they run.

FAQ

Questions we hear most.

If yours isn't answered here, reach out at support@sifrsys.com.

Every AI query is fenced by Row-Level Security at the database level. When a participant asks a question, the AI retrieves only from documents within their permission boundary. It cannot access, reference, or learn from documents outside that boundary, and nothing is ever used for model training.
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, so participants can revisit their cited answers.
Every AI answer includes clickable citations that link to the exact page in a PDF or the exact cell range in a spreadsheet. Click a citation and you're taken directly to the source passage. Participants verify AI statements themselves — they don't need to trust the AI on faith.
Room Intelligence is an AI deal advisor built into every data room. It tracks who viewed what, identifies which contacts at which groups 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.
When a participant asks the AI a question, the retrieval system only searches documents that participant has been granted access to. This is enforced at the database level using Row-Level Security — not application-level filtering. The AI literally cannot see documents outside a participant's permission boundary, even if they exist in the same data room.
Sifrsys parses and indexes PDF, DOCX, XLSX, PPTX, and other common document formats automatically — no manual conversion needed. Financial terms are expanded for better retrieval accuracy.
Four tiers: Starter (free — 1 room, 100 MB, 5 participants), Teams ($399/mo, 3 rooms, 1 GB), Pro ($999/mo, 10 rooms, 5 GB), and Enterprise (custom pricing, 100 rooms, 50 GB). There are no per-page fees, no storage surcharges, and no surprise costs. Every plan includes AI capabilities.
You can create a data room and start uploading documents in minutes. Documents are automatically parsed and indexed for AI retrieval. Invite participants with passwordless access — they get a magic link and are in immediately.
Yes. Every data room includes a branded portal with custom subdomain, logo, and colors. Participants access the portal on a clean, branded URL — no Sifrsys branding visible to them unless you want it.
Every action in the data room is recorded in a hash-chained audit log, where each entry cryptographically references the previous one. This makes the log tamper-proof and verifiable. You can export the full audit trail as CSV or JSON and verify chain integrity at any time.
Page-level tracking shows exactly which pages each participant viewed and for how long. Engagement scoring ranks participants by activity. Heatmaps visualize attention patterns across documents. 14-day trend analysis shows engagement direction. Room Intelligence layers AI interpretation on top of all this data.
Yes. The Starter plan is completely free and includes 1 data room, 100 MB storage, AI document Q&A, and 5 participants. No credit card required. You can upgrade to Teams, Pro, or Enterprise as your needs grow.
