Reference
Industry Glossary
Plain-language definitions for the terms that come up in every proxy and data conversation.
Residential Proxy
An IP address assigned by a consumer internet provider, routed through a real household connection — far harder to distinguish from ordinary traffic.
Datacenter Proxy
An IP originating from a hosting facility. Fastest and cheapest, but easily identified as non-consumer traffic.
Mobile Proxy
An IP from a cellular carrier network. Highest trust level because carrier IPs are shared across many legitimate users.
Sticky Session
A configuration that keeps the same IP for a set duration, so multi-step workflows aren't broken by mid-session rotation.
IP Rotation
Automatically cycling through a pool of addresses to distribute request volume and avoid per-IP rate limits.
Backconnect Proxy
A single gateway endpoint that transparently routes each request through a different IP from the underlying pool.
Data Enrichment
Appending additional verified fields — firmographics, contacts, technographics — onto an existing record set.
Data Decay
The natural degradation of contact accuracy over time, typically 25–30% per year as roles and companies change.
Lawful Basis
The legal justification required under GDPR before personal data may be collected or processed — established before acquisition.
p95 Latency
The response time that 95% of requests fall under. Far more meaningful than an average, which hides tail performance.
Concurrency Limit
The maximum number of simultaneous connections permitted on a plan, distinct from total monthly request volume.
Uptime SLA
A contractual availability guarantee, usually with service credits owed when the stated threshold is missed.
MERN Stack
MongoDB, Express, React, and Node.js — a single-language JavaScript stack covering database through user interface.
NoSQL / Document Database
Storage that keeps flexible JSON-like documents rather than fixed table rows, so the schema can evolve without migrations.
Server-Side Rendering (SSR)
Generating HTML on the server before it reaches the browser — faster first paint and far better search engine indexing than client-only rendering.
Reverse Proxy
A server such as Nginx that sits in front of your application, routing requests, terminating SSL, and balancing load across instances.
Containerization
Packaging an app with its dependencies (via Docker) so it runs identically on a laptop and on a production VPS.
VPS
A virtual private server — dedicated, predictable resources at a fixed monthly cost, without hyperscaler pricing or vendor lock-in.

Frequently Asked Questions
Everything you need to know before getting started with Nurvel Networks.
We offer residential, datacenter, and mobile proxies with flexible rotation options across 195 countries. Residential proxies come from real user devices, datacenter proxies offer the highest speed, and mobile proxies provide the best anonymity for demanding use cases.
Standard datasets maintain 90%+ accuracy, while premium and custom packages reach 95–98%. All records go through a multi-stage AI-assisted verification pipeline before delivery.
Yes — we offer a limited free trial for proxy services. Reach out via the contact form and mention 'free trial' to get started with no commitment required.
Web and app development: 4–12 weeks. Standard data packages: 24–72 hours. Custom mining projects: 1–2 weeks. We always confirm timelines upfront before work begins.
We are ISO 27001 certified with strict data handling protocols. We never sell or share your usage data. All traffic is encrypted in transit and at rest.
Yes, plan changes take effect immediately with prorated billing. Upgrade, downgrade, or cancel anytime from your dashboard or by contacting our support team.
Yes. Sticky sessions hold the same IP for up to 30 minutes, configurable per request via the session parameter. This is essential for multi-step workflows like login flows or paginated navigation.
Our adaptive routing engine scores every route continuously and pulls degraded nodes automatically. Failed requests are retried transparently through a healthy route, so failure rates stay under 0.8% in production.
Every dataset carries a full provenance audit trail. We establish lawful basis before acquisition — legitimate interest for B2B records with a documented balancing test and functioning opt-out path — and we operate under GDPR and CCPA frameworks.
Basic packages refresh monthly, premium weekly, and custom tiers support real-time updates via API. Because contact data decays roughly 25–30% per year, we strongly recommend a refresh cadence rather than a one-time purchase.
We accept major credit cards, wire transfer, and ACH. Invoicing in USD, EUR, GBP, AED, and PKR is available, and enterprise accounts can arrange net-30 terms.
Proxy plans carry a 7-day money-back guarantee if you've used under 10% of allocated bandwidth. Data purchases are refundable where delivered accuracy falls materially below the tier commitment.
ISO 27001 certified and SOC 2 Type II audited, with GDPR and CCPA compliance programs. Our infrastructure is PCI DSS Level 1 aligned and we support HIPAA-aligned handling for healthcare datasets.
Yes. Regional data residency controls are available, letting EU customers keep processing and storage entirely within EU jurisdictions. Residency is configurable at the account level.
All plans get a guaranteed response within 4 business hours. Business and Enterprise tiers add 24/7 coverage, a named account manager, and direct access to the engineers who built the platform — not a scripted first-line queue.
Yes, and at no cost. We map your existing configuration, run both setups in parallel during transition, and stage the cutover so there's no interruption to production traffic.
