Egress Control Plane

Proxies Are An
IP Address
Access Plane

Most teams treat proxies as "get an IP in the right country." That mindset causes predictable failure: unstable success rates, proxy waste from retries, and escalating cost as targets harden.

Why Proxies Matter
Even With Perfect Stealth

Even with Chromium-level evasion and coherent fingerprints, egress still carries risk signals. At scale, proxies are rarely the root cause of success, but they are often the root cause of unstable variance, cost blowouts, and non-reproducible failures.

Reputation & History

IP and ASN reputation signals persist across sessions and time.

Geo & Carrier Plausibility

Network egress must align with identity locale and device class.

Concurrency Density

Too many sessions from the same subnets creates correlation risk.

Failure Amplification

Retries on degraded routes multiply cost without improving outcomes.

Proxy Cost Trajectory Uncontrolled
Controlled Naive TARGET HARDENS
Controlled Routing Baseline +12%
Random + Retry +340% cost

The correct goal is not "more proxies." It is controlled routing and predictable outcomes .

Operational Model

Optional, Volume-Priced,
Policy-Driven

Undetect treats proxies as an operational control plane: optional if you already have procurement, cost-advantaged if you don't, deeply integrated with routing and identity strategy.

Recommended

Proxy Panel

Volume-Based Rates

Large proxy panel with volume advantages passed through. For many teams, proxy savings offset a meaningful portion of platform cost, especially accounting for avoided retry waste.

  • Lower effective cost per GB / session
  • Fewer vendors to manage
  • Predictable performance classes
  • Global coverage across 195 countries
Often offsets 30-50% of platform cost

BYO Proxies

Proxy-Agnostic Design

Enterprises frequently have pre-approved vendors, internal egress controls, compliance constraints, and negotiated contracts. Undetect does not force the panel.

  • Use existing vendor relationships
  • Maintain compliance constraints
  • Leverage negotiated contracts
  • Full routing and policy tooling
Mix our panel and BYO

Hybrid Deployments

Most mature teams end up mixing: panel for breadth and experimentation, BYO for tightly controlled production routes. Undetect supports both simultaneously with unified policy management.

Selective Routing

Routing Is Where
Real Leverage Lives

Naively routing every request through premium egress is expensive and often slower. The correct approach is selective risk allocation.

Per-URL Routing

Many targets have a small set of endpoints that drive majority scrutiny. Use premium, higher-reputation routes only on high-risk endpoints; cheaper routes on low-risk assets.

// Route configuration
routes:
- pattern: "/login"
class: premium-residential
- pattern: "/api/*"
class: standard-residential
- pattern: "/static/*"
class: cost-optimized
Typical reduction: 40-60% proxy spend

Policy-Based Selection

At scale you need routing policies you can reason about: region and carrier class selection, performance class, failover behavior, controlled rotation vs persistence.

Proxies and Identity
Must Agree

A subtle but common mistake is treating proxy choice and fingerprint choice as independent. Modern systems correlate geo, language, timezone, and locale with network egress; device class with ASN patterns; account history with consistent network behavior.

Contradiction Risk

German identity + Brazilian egress + English browser language = elevated scrutiny

Reduce Waste.
Increase Throughput.

Proxy costs typically explode because teams cannot see where waste comes from. Undetect emphasizes operational clarity so you can identify bottlenecks and maintain predictable cost per successful session.

Bottleneck Identification

See degradation by target, route, and endpoint class. Distinguish proxy issues from application issues from target changes.

Retry Amplification Control

Understand when retries are helping vs. multiplying cost. Route around degraded paths instead of hammering them.

Cost Per Success

Track true unit economics: not cost per request, but cost per successful, complete session with full data extraction.

Proxy Panel is a fit if...

  • 01

    Want cost-advantaged rates without multi-vendor procurement

  • 02

    Need coverage across many regions quickly

  • 03

    Want single operational model and support path

BYO is a fit if...

  • 01

    Already have contracts and internal compliance requirements

  • 02

    Require fixed egress and strict network controls

  • 03

    Have existing routing infrastructure you want to keep
