Protect files before sharing them.
SentinelLolge is built around the moment a file leaves you. Use the protect workflow to prepare a browser-based protected delivery asset before the file is emailed, uploaded, or handed to someone else.
Standard browser-first path
Protect the file locally in your browser and export a self-contained unlock experience that can travel with the document.
Stricter controlled delivery
When needed, pair the handoff with expiry, read-only access, unlock limits, or recipient-aware checks.
Designed for real business files
Use it for PDFs, contracts, invoices, proposals, reports, archives, and other sensitive documents that should not become raw open attachments.

Guide / Product overview
What is SentinelLolge?
SentinelLolge is a browser-first file protection product from Lolge Labs for people who need to protect files before sharing them. It is built around the delivery moment: before a file is emailed, forwarded, copied, or sent outside the system where it was originally stored.
Protect before sharing
SentinelLolge helps the sender prepare a protected delivery experience first, so the protection can move with the file instead of depending on a separate portal later.
Browser-first workflow
The standard flow keeps original file contents local in the browser while producing a protected unlock package that recipients can open in modern browsers.
Controlled delivery paths
When a use case needs more than a simple protected handoff, stricter workflows can add expiry, unlock limits, read-only behavior, and recipient-aware access checks.

Guide / Secure sharing
Protect files before sharing them
If a file matters after it leaves your inbox, protect it before sharing it. SentinelLolge is designed for contracts, spreadsheets, reports, source archives, customer documents, and other private assets that should not become unprotected raw attachments after download.
Why it matters
Once a raw file is sent, the sender usually loses control over forwarding, copying, or reuse. Protecting the file before sharing helps keep confidentiality attached to the delivery asset itself.
How SentinelLolge helps
The product prepares a protected unlock experience first, then lets you share that result instead of the original raw file.
When to use it
Use this route when the file contains sensitive business information, client records, internal review notes, payment material, or any document that should not circulate freely after handoff.
Guide / PDF protection
Protect PDF files before sharing
PDFs are one of the most common formats for invoices, proposals, agreements, policies, and customer documents. SentinelLolge helps protect a PDF before sharing it so the sender is not relying on the recipient to handle the raw file securely afterward.
Good use cases
Protect invoices, pricing sheets, board packs, signed agreements, and review copies before sending them outside your own team.
Preview-friendly delivery
PDF-based workflows fit well with preview-oriented unlock experiences where the chosen rules allow it, making the protected handoff easier for recipients.
Expiry and access rules
For stricter workflows, you can pair the protected PDF delivery path with expiry schedules, unlock limits, or read-only behavior before the document is sent.
Guide / Delivery control
Secure file delivery for sensitive documents
Secure file delivery is about more than storing a file safely. It is about how the document is handed off, what the recipient sees, what rules travel with the file, and how much control the sender keeps after sharing. SentinelLolge is built around that delivery moment.
Delivery-focused protection
The workflow protects the document before it leaves you, so the handoff itself is controlled instead of depending only on the security of the destination system.
Standard and strict paths
Use the standard browser-first delivery flow for offline-friendly protection, or choose stricter delivery controls when you need expiry, unlock rules, or recipient-aware access steps.
Fits real business handoffs
This route is useful for investor materials, customer reports, legal documents, vendor exchanges, design handoffs, and financial records that need stronger control during delivery.
Guide / Intended-recipient delivery
Intended-recipient delivery and stricter access checks
Some protected files should only be opened by the intended person, not simply anyone who receives the package. SentinelLolge supports stricter delivery workflows for senders who want stronger intended-recipient control around sensitive handoffs.
Why it matters
Confidential files are often sent to a named reviewer, signer, or customer contact, yet plain attachments are easy to forward. Recipient-aware controls help align document access with the intended audience.
What this helps with
Use it for customer-specific reports, approval packets, renewal terms, employee paperwork, and procurement documents where a plain password on a raw file is not enough.
Practical limit
The goal is stronger delivery discipline and intended-recipient control. It should not be treated as a guarantee against every forwarding, capture, or endpoint-side risk.
Guide / Expiry controls
File expiry links and time-limited document access
Some documents should only stay available during a review window, an approval deadline, or a short-lived client exchange. SentinelLolge supports protected delivery paths where expiry is part of the file-sharing workflow instead of an afterthought.
Reduce long-tail exposure
Expiry helps lower the chance that an old shared document stays accessible indefinitely after the reason for sharing has ended.
Good fits
Use it for short review cycles, temporary customer approvals, expiring invoice access, diligence material, and one-time protected document delivery.
Works with stricter rules
Pair time-limited access with unlock limits, read-only behavior, or recipient-aware controls when the document sensitivity requires a tighter handoff.
Finance workflow
Protect invoices before sending them
Invoices often include customer details, payment information, and approval context that should not remain exposed after delivery. SentinelLolge helps teams protect invoices before sending them so the invoice handoff stays controlled.
Safer invoice delivery
Share a protected delivery asset instead of a raw invoice attachment that can be forwarded or stored indefinitely.
Fits finance review windows
Use expiry-aware delivery when invoices, statements, or billing packs only need to stay available during a short approval or payment cycle.
Useful for client-facing billing
This route fits client invoices, payment summaries, credit notes, and finance records that should stay protected after they leave your team.
Legal workflow
Protect contracts before emailing them
Contracts move through review threads, approvals, and external inboxes where plain attachments are easy to forward. SentinelLolge helps legal and commercial teams protect contracts before emailing them so the agreement stays controlled after the send.
Built for email-heavy reviews
Use a protected delivery path instead of sending the raw agreement first and hoping the thread stays private.
Supports recipient-aware delivery
Stricter workflows can help align access with a named reviewer, signer, or customer contact when a contract should not be broadly opened.
Useful for agreements and renewals
Use it for MSAs, vendor contracts, employment agreements, renewal terms, and other legal files that need tighter handoff control.
Confidential sharing
Share confidential documents securely
Confidential files should stay controlled after the send, not just while they are stored internally. SentinelLolge helps teams share confidential documents securely by protecting the file before it leaves the sender.
Designed for sensitive files
Use it for legal documents, finance packs, customer records, board materials, credentials, and private reports.
Works from simple to strict
Start with browser-first protected delivery, then add expiry, unlock rules, or recipient-aware checks for higher-risk handoffs.
Keeps protection close to the asset
The workflow is built so confidentiality travels with the document instead of depending entirely on where the recipient stores it.
Client delivery
Send secure client files
Client documents often include exactly the material that should stay controlled after delivery: invoices, reports, contracts, approvals, and private records. SentinelLolge helps you send secure client files without relying on raw attachments alone.
Fits recurring client handoffs
Use it for billing documents, onboarding packs, monthly reports, signed paperwork, and customer-specific approvals.
Good for expiring access
Pair client delivery with expiry when access should end after the review, approval, or payment window closes.
Supports named-recipient delivery
Use stricter controlled access when a particular customer contact or reviewer should be the one opening the protected file.
