Traffic from VPN/proxy exits requires heightened scrutiny; consider CAPTCHA or secondary verification for sensitive operations.

Recommendation: apply conditional access for 212.56.47.88. VPN/proxy traffic is not inherently malicious — many legitimate users rely on VPNs for privacy — but for geo-restricted content or fraud-sensitive flows, require additional verification before granting access.

This IP is classified as a proxy/VPN exit — assume that any request from it originates from an unknown real location. For fraud-sensitive workflows (payments, account creation), request secondary verification. For non-sensitive browsing, consider allowing access but logging the IP for audit.
