Security Review Template for Third-Party Scraper Integrations and Micro Apps

Hook: Why your next data breach will likely come from a micro app

Security teams are already stretched. You need reliable data for analytics and AI, but you also face a rising tide of third-party apps and ephemeral micro apps that ingest or expose scraped data — many built by non-developers with generous permissions and few security controls. In 2026, attacks and accidental exposures increasingly originate in these thin, fast-moving integrations. This guide gives security teams a practical, prioritized security review template—an auditable checklist to evaluate third-party micro apps and APIs that ingest or expose scraped data, covering auth, data handling, and incident response.

Executive summary (most important first)

Perform a rapid triage (5–15 minutes) on any micro app or API before allowing it to connect to your environment:

• Can it prove identity and follow least-privilege auth? If not, block.
• Is all sensitive scraped data encrypted in transit and at rest? If not, restrict data flows.
• Does the vendor have an incident response (IR) plan, SLA for breaches, and forensic logs? If not, require written commitments.

Below is a full, actionable checklist sandboxed into onboarding, technical tests, legal/compliance checks, operational controls, and incident response playbook items. Use it as a gate, a periodic review tool, and a runbook for investigations.

The 2026 context: Why this matters now

Several trends through late 2025 and early 2026 make this checklist essential:

• Micro apps proliferation: Low-code/AI-assisted “vibe-coding” means more non-engineered apps—rapidly built, often by non-developers, that still request access to sensitive datasets.
• Autonomous agents and desktop access: New agent tools that can access file systems and APIs increase the attack surface for scraped data exfiltration.
• Heightened regulatory scrutiny: Privacy regulators and enterprise auditors expect strong controls on data lineage, retention, and breach notification—expect tighter audits in 2026.
• Data quality and trust hurdles: Enterprises repeatedly cite weak data management as an AI scaling blocker—uncontrolled third-party ingestion compounds that issue.

How to use this template

This template is divided into practical sections:

1. Quick triage (0–15 min) — gatekeeping questions to block risky apps fast
2. Deep technical evaluation (1–3 days) — tests and artifact requests
3. Policy, legal & compliance checks — contractual and regulatory must-haves
4. Operational controls — monitoring, deployment, and lifecycle management
5. Incident response & forensics — playbook and post-incident steps

Quick triage checklist (0–15 minutes)

Use these to make an immediate allow / deny / quarantine decision.

1. Source validation: Is the app/vendor identity verifiable (corporate domain, MSA, legal entity)? If it's a personal or anonymous micro app, deny or put into quarantine.
2. Purpose & data scope: Exactly which scraped data fields will the app access? If the scope is broad or ambiguous, require narrowing or deny.
3. Auth type: Does the integration use an industry-standard auth flow (OAuth2 with server-side token exchange, mTLS, or signed JWTs)? Client-side API keys or embedded secrets are high risk.
4. Least privilege: Are requested permissions scoped and time-boxed? Reject if the app requests global or admin-level data access.
5. Network posture: Does the app call back to unknown hosts or require inbound firewall openings? If yes, deny or require a secure proxy.

Deep technical evaluation (1–3 days)

This section lists concrete tests, artifacts to request, and red flags to watch for.

Authentication & authorization

• Require OAuth2 authorization code flow with PKCE for browser-based micro apps; require client credentials flow with mTLS for service-to-service.
• Validate token lifetimes and refresh patterns. Tokens should be short-lived (minutes to hours) with automated rotation.
• Inspect any JWTs for weak signing algorithms (no HS256 when using shared secrets in public clients) and confirm the use of asymmetric keys where appropriate.
• Confirm support for scope-based authorization and role mapping. Test that token scopes actually restrict API calls in practice (negative tests).
• Check for embedded secrets in client-side code, mobile apps, or browser extensions using static analysis or SCA tools.

Network & API security

• Enforce TLS 1.2+ (TLS 1.3 preferred) with strong ciphers. Reject endpoints that accept weak/TLS downgrade connections.
• Require API gateway or WAF in front of any public endpoints. Confirm rate limits and quota enforcement to prevent scraping amplification or DDoS.
• Validate input sanitization, JSON schema enforcement, and size limits—protect against injection or resource exhaustion.
• Check CORS and CSP headers for web apps to limit unwanted cross-origin data access. For browser extensions, inspect permissions and content scripts carefully.

Data handling & storage

• Require encryption in transit and at rest. For sensitive scraped fields (PII, payment info, proprietary datasets) require field-level encryption and key separation.
• Ask for data flow diagrams and a data map showing how scraped content moves from ingestion to long-term storage, backups, and downstream consumers.
• Confirm separation of environments (dev/test/prod) and that scraped production data is not used in test environments without obfuscation.
• Validate retention and deletion policies. Ensure they support legal requirements (e.g., GDPR access/delete) and include automated deletion controls.
• Request details on anonymization/pseudonymization methods and a risk assessment for re-identification.

Logging, observability & tamper resistance

• Require immutable logs for auth events, API calls, and data exports. Logs should include requestor identity, IP, scope, and a cryptographic timestamp if possible.
• Confirm logs are shipped to a centralized SIEM and retained for an agreed period for investigations.
• Test alerting—supply a simulated anomaly (excessive export) and validate that alerts fire and integrate with your incident workflow.

Software supply chain & code assurances

• Request SBOMs and dependency scans (Snyk, OSS-Fuzz, GitHub Dependabot reports). For 2026, supply-chain integrity is non-negotiable.
• Ask for recent penetration test reports and remediation tickets or proof of fixes. For micro apps, require at least an automated SAST/DAST scan and responsible disclosure policy.
• Validate CI/CD pipeline security: signed builds, ephemeral credentials, secrets scanning, and deployment approvals.

Policy, legal & compliance checks

Legal controls reduce business risk. Don’t skip contract-level protections.

• Data processing agreement (DPA): Must specify permitted uses, subprocessor lists, security controls, incident notification timelines, and audit rights.
• Right to audit: Ensure contractual audit windows, on-site or remote audits, and the right to request evidence of compliance (SOC 2, ISO 27001).
• Breach notification SLA: Contract an explicit timeline (e.g., 72 hours or faster) and responsibilities for legal/regulatory notifications.
• Liability & indemnification: Define limits and cover cases of third-party scraping misuse, IP violations, and regulatory penalties where appropriate.
• Regulatory mapping: Verify how the vendor handles data in the context of GDPR, CPRA/CCPA, sector rules (e.g., HIPAA when healthcare data is involved), and cross-border transfers.

Operational controls & lifecycle management

Even secure apps degrade if left unmanaged. Define operations, lifecycle, and decommissioning rules.

• Onboarding checklist: Use this template as a required intake form for every third-party micro app. Include technical, legal, and business contacts.
• Least-privilege access reviews: Quarterly access reviews and automated revocation for inactive tokens/clients.
• Monitoring: Integrate third-party telemetry into your SIEM/SOAR. Monitor abnormal exports, new endpoints, or changes to scopes/permissions.
• Deprovisioning: Automatic revocation of credentials when a micro app is disabled and a documented secure data purge plan.
• Change control: Require notifications and re-review for code changes that affect auth, data handling, or data mapping.

Incident response: playbook for scraped data exposures

Incidents involving scraped data require specialized steps. Use this playbook and checklist during a real incident.

Immediate containment (0–4 hours)

1. Revoke or rotate compromised credentials and remove OAuth client approvals. Prefer automated revocation via API.
2. Block or quarantine offending IPs or hosts at the gateway or WAF. For agent-based apps, kill sessions and isolate endpoints.
3. Preserve volatile forensic evidence (memory, sockets) and take snapshots of affected systems. Note the chain of custody.

Triage & scope determination (4–24 hours)

1. Use logs to enumerate affected records, exports, and downstream consumers. Prioritize exposures by sensitivity and regulatory impact.
2. Engage vendor immediately and request full audit logs, export manifests, and list of sub-processors.
3. Start a timeline: when the app connected, who authorized it, and what data flows occurred.

Notification & legal steps (24–72 hours)

1. Follow contractual breach-notification timelines. Include regulators and affected data subjects where required by law.
2. Coordinate with privacy, legal, and communications teams to craft messaging that balances transparency and legal risk.
3. Consider disclosure to platform owners when scraping violates a protected service's terms—this can be required for cooperative remediation.

Remediation & follow-up (72 hours to 90 days)

1. Deploy fixes: patch vulnerabilities, harden auth flows, and reconfigure permissions. Validate with retests and a third-party pen test if needed.
2. Implement compensating controls: stricter rate limits, additional DLP rules, or staged access with approval workflows.
3. Do a post-incident review with stakeholders and update onboarding, policy, and technical controls. Retain lessons learned in the vendor file.

Red flags that should trigger denial or escalated review

• Vendor refuses to provide DPA, breach SLA, or SOC/ISO evidence.
• Embedded keys or secrets in client-side code or public repos.
• No centralized logs, or logs are easily alterable (no immutability).
• Requests for full-scope admin or mass export privileges without a clear business justification.
• Unverified or anonymous developer identity for apps that access proprietary or regulated scraped data.

Practical templates & artifacts to request (copy-paste)

Ask vendors for these artifacts during onboarding—use them as acceptance criteria:

• Data Flow Diagram for scraped data (ingest → transforms → storage → exports)
• OAuth/OpenID configuration and token lifetime policy
• SBOM and dependency vulnerability scan within the last 90 days
• SOC 2 type II or ISO 27001 certificate (or equivalent evidence)
• Incident response plan with breach notification timeline
• Recent pentest report and remediation summary

Case study (concise, real-world lesson)

In late 2025, a mid-market analytics firm adopted several micro apps to accelerate feature engineering. One micro app requested broad read access to scraped product catalogs and had an embedded API key in its frontend. Within weeks, an exposed key enabled a scraper bot to mass-export product feeds, leading to a data leak and downstream model poisoning. The firm had no DPA and discovered the breach only after an external vendor reported suspicious activity. Lessons learned: enforce server-side token exchange, require DPAs, and scan for secrets in any public or packaged app before approval.

2026 advanced strategies and future-proof controls

Beyond the checklist, adopt these forward-looking measures for 2026 and beyond:

• Zero Trust for APIs: Micro-segmentation of API traffic, continuous authentication checks, and per-call policy enforcement.
• Data provenance & cataloging: Use a data catalog that tracks the origin of scraped records and tags lineage to the app that accessed them. This speeds forensics and compliance.
• Automated attestation: Require automated attestations for each third-party app (build signatures, SBOM freshness, vulnerability thresholds). Use orchestration to revoke access when attestations fail.
• Agent & desktop governance: For AI agents or desktop micro apps that request local file system access, require host-based controls (EDR policies, confinement, and explicit human approval flows).
• Continuous risk scoring: Use an external vendor-risk platform that continuously scores third-party apps against threat feeds, misconfiguration, and newly published vulnerabilities.

Checklist summary (one-page gate)

1. Vendor identity & DPA present
2. OAuth/mTLS auth; no client-embedded secrets
3. Least-privilege scopes and token rotation
4. Encryption in transit & at rest; field-level for sensitive data
5. Centralized immutable logs & SIEM integration
6. SBOM & recent dependency scans; pentest evidence
7. Breach SLA ≤ 72 hours and legal contact provided
8. Onboarding completed and quarterly access reviews scheduled

Final recommendations for security teams

Implement this template as a mandatory part of your vendor intake process. Use automation where possible: deny integrations that fail static checks (embedded secrets, expired certs) and flag apps that require manual review. Schedule periodic re-certification (90 days for high-risk apps, 12 months for low-risk) and embed the review into procurement and DevOps workflows.

Remember: The fastest micro app is valuable—until it becomes the fastest way for attackers to exfiltrate your scraped data. Treat each micro app as an endpoint and each API as a potential supply-chain vector.
