How long does the integration take?

Change one base URL in an OpenAI-compatible client, or install the Python or TypeScript SDK; the quickstart routes a first request in a few minutes.

Will this lock us into another vendor?

No. The router is Apache-2.0 open source, your provider keys stay yours, and the API is OpenAI-compatible, so leaving is a change of base URL.

What happens when a provider fails?

The router falls back to the next model your policy allows and records the fallback in the trace, so an outage costs a retry, not an incident.

Implementing Email Sandboxing with Proofpoint

Overview

Email sandboxing detonates suspicious attachments and URLs in isolated environments to detect zero-day malware and evasive phishing payloads. Proofpoint Targeted Attack Protection (TAP) is an industry-leading solution that uses multi-stage sandboxing, URL rewriting, and predictive analysis. This skill covers configuring Proofpoint TAP, integrating with email flow, analyzing sandbox reports, and tuning detection policies.

When to Use

When deploying or configuring implementing email sandboxing with proofpoint capabilities in your environment
When establishing security controls aligned to compliance requirements
When building or improving security architecture for this domain
When conducting security assessments that require this implementation

Common Misconfigurations & Verification

Detonation timeout too short: time-bomb malware delays execution past the analysis window - set the sandbox timeout high enough (60s+) and rely on TAP predictive analysis for known-evasive families.
URL-only lures slip through: credential-phishing pages with no attachment aren't caught by Attachment Defense - confirm URL Defense rewriting + time-of-click sandbox is enabled on ALL inbound mail, not just attachments.
No dynamic delivery: holding the whole message until verdict frustrates users and invites bypass requests - enable dynamic delivery (release body, hold attachment until verdict).
Password-protected archives skipped: encrypted .zip/.7z bypass detonation unless the engine harvests the password from the body - enable password attempt, then quarantine on failure.
Allowlists too broad: blanket domain/sender bypass lists become a hole attackers abuse - scope bypasses narrowly and review them.
TAP not wired to SIEM/TRAP: verdicts arriving after delivery do nothing without auto-pull - confirm Threat Response Auto-Pull retracts post-delivery and TAP events export to SIEM.
Verification: submit the EICAR test file, a macro-enabled doc, and a known-phishing URL; confirm the attachment is detonated and quarantined, the URL is rewritten and blocked at click, and a post-delivery weaponized URL is auto-retracted.

Prerequisites

Proofpoint Email Protection license with TAP add-on
Admin access to Proofpoint admin console
Understanding of email delivery architecture (MX records, mail flow rules)
SIEM integration capability

Key Concepts

Proofpoint TAP Capabilities

Attachment sandboxing: Detonates files in virtual machines (Windows, macOS, Android)
URL Defense: Rewrites URLs, detonates at time-of-click
Threat Intelligence: Proofpoint's NexusAI threat intelligence integration
TAP Dashboard: Real-time visibility into threats targeting the organization
Campaign correlation: Groups related attacks into campaigns
Very Attacked People (VAP): Identifies most-targeted individuals

Sandbox Evasion Techniques Detected

Delayed execution (time-bomb malware)
VM detection bypass
User interaction requirements (click-to-enable macros)
Sandbox-aware malware that checks for analysis environment
Encrypted/password-protected attachments
Multi-stage payloads with delayed C2 retrieval

Workflow

Step 1: Configure TAP in Proofpoint

Enable TAP for inbound email policy
Configure sandbox profiles (attachment types to detonate)
Set URL Defense rewriting policy
Configure quarantine actions for malicious verdicts

Step 2: Tune Attachment Policies

Recommended attachment policy:
- Detonate: .exe, .dll, .scr, .doc(m), .xls(m), .ppt(m), .pdf, .zip, .rar, .7z, .iso
- Block without detonation: .bat, .cmd, .ps1, .vbs, .js, .wsf, .hta
- Password-protected archives: Attempt common passwords, then quarantine
- Dynamic delivery: Deliver email body, hold attachment until verdict

Step 3: Configure URL Defense

Enable URL rewriting for all inbound email
Set time-of-click detonation
Block access to malicious URLs
Show warning page for suspicious (not confirmed malicious) URLs
Configure allowed domains bypass list

Step 4: Set Up TAP Dashboard Monitoring

Configure daily threat digest emails to security team
Set up real-time alerts for targeted attacks
Monitor VAP report for high-risk users
Review campaign clusters for coordinated attacks

Step 5: Integrate with SIEM

Configure syslog/API export to SIEM
Create correlation rules for TAP alerts
Set up automated response workflows

Install implementing-email-sandboxing-with-proofpoint and it becomes one more candidate the router can pick - when it fits.

A listing is a routing target with a manifest: what it does, which domains it covers, what it costs and who publishes it. Once installed it sits beside your own models and tools, is scored like any other candidate for each request, and shows up in the trace when it wins. Ratings come from workspaces that installed it, one per account.
