What it does
Implementing Email Sandboxing With Proofpoint is an agent skill from mukul975/Anthropic-Cybersecurity-Skills. 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
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including scripts, reference files and assets (for example `assets/template.md`, `references/api-reference.md` and `references/standards.md`).
It sits in Security. The repository describes itself as: 817 structured cybersecurity skills for AI agents · Mapped to 6 frameworks: MITRE ATT&CK, NIST CSF 2.0, MITRE ATLAS, D3FEND, NIST AI RMF & MITRE F3 (Fight Fraud) · agentskills.io…. The licence is Apache-2.0.
When your agent uses it
- Security work in your project
Example prompts
- “/implementing-email-sandboxing-with-proofpoint”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 54a7988. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 2 files in scripts/ (Python), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
proofpoint.comthreatinsight.proofpoint.comhelp.proofpoint.comcommunity.proofpoint.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Implementing Email Sandboxing With Proofpoint loads about 1.1k tokens when it runs, and up to ~2.3k if it reads all its reference files. Until then it costs about 62 tokens; SKILL.md has 386 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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
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
Show full SKILL.md (169 more words)Show less
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 verdictStep 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

- Proofpoint Community: https://community.proofpoint.com/
Validation
- Attachment detonation catches EICAR test file and macro-enabled document
- URL Defense rewrites and blocks known phishing URLs
- TAP Dashboard displays threat summary
- SIEM receives and alerts on TAP events
