The MSP Challenge

Security outcomes at scale are hard to deliver manually.

MSPs are expected to provide security outcomes, not just tooling. Clients want to know their environments are protected and that incidents are being handled.

When clients ask what happened to their phishing report, the honest answer is often that nobody checked. Reporting mailboxes sit unreviewed. End users hear nothing. Reporting behavior deteriorates.

Manual triage doesn't scale across a book of clients. Analysts spend time on low-confidence reports that could be handled automatically — time that should go toward genuine incidents.

Without Sentinel
Reports accumulate unreviewed. Clients receive no triage results. Analysts are pulled into manual review of emails that fall well below incident threshold. End users stop reporting after receiving no response.
With Sentinel
Every report is analyzed automatically. End users receive explanations immediately. Analysts receive structured triage summaries for the reports that need attention. Reporting rates improve as users see value in the process.

MSP Benefits

What Sentinel delivers for managed service providers.

Operational efficiency for your team. Measurable security outcomes for your clients.

⚙️
Automated Triage at Scale
Each client's reporting mailbox is monitored continuously. Every reported email receives deterministic analysis without analyst intervention. Triage happens automatically across all clients simultaneously.
👤
End User Feedback Loop
Users receive plain-language explanations of why an email was or wasn't suspicious. Feedback improves reporting behavior over time, which means your clients' users report more and ignore less.
📦
Lightweight Container Deployment
Sentinel runs as a Docker container. Minimal infrastructure footprint. No additional hardware. No complex dependencies. Deploy inside client infrastructure on a schedule that fits your onboarding process.
🏢
Multi-Client Architecture
Independent instances per client. No shared infrastructure, no cross-client data exposure. Each environment operates entirely within the client's own boundary. No data lake of client email content.
🛡️
No Retention Risk
Email content is processed in memory and discarded. Sentinel does not create a searchable archive of client email. Report metadata is logged; message content is not. Reduces data handling obligations significantly.
📊
Structured Analyst Escalations
When reports warrant analyst attention, the escalation arrives as a structured analysis — not a raw forwarded email. Analysts have context before they open the message. Investigation starts faster.

Deployment

Simple to deploy. Simpler to maintain.

Ephemeral Sentinel is designed to fit inside standard MSP deployment workflows without requiring new infrastructure or complex integrations.

🐳
Container Deployment

📬
Mailbox Integration
Connects to the existing reporting mailbox via IMAP. Compatible with Microsoft 365, Google Workspace, and self-hosted mail servers.
🔧
Minimal Configuration
IMAP credentials, polling interval, and report delivery address. No complex configuration required. No agents installed on endpoints.
🚀
No Mail Flow Changes
Does not sit inline with email delivery. No MX record changes. No risk to mail flow reliability. Invisible to daily operations.
🔒
Firewall Friendly
Outbound IMAP only. No inbound ports required. Compatible with even the most restrictive client firewall configurations.
⚖️
Low Maintenance Overhead
No AI models to update. No external service dependencies to manage. Deterministic rule engine requires no retraining or tuning.

Client Experience

What your clients' users receive.

When an employee at one of your client organizations reports a suspicious email, they receive a structured analysis reply within seconds.

The report explains in plain language what signals were detected, what attack technique was identified, and what action to take. No security background required to understand the output.

Your analysts receive a parallel copy of the same report, with full technical detail. If the report warrants action, they have everything they need to begin an investigation immediately.

Attack Narrative
Callback phishing attempt impersonating a software vendor. Victim instructed to call a fraudulent support number to dispute a fabricated charge.
Recommended Action
Do not call the number or interact with any links. Mark as phishing and delete.
