Data masking vs encryption: how they differ and when to use eachCompares data masking (irreversible, keeps data usable) and encryption (reversible with a key, but unusable until decrypted), covers tokenization and anonymization as related techniques, and maps all four onto stages of a data pipeline, arguing most programs combine several rather than picking just one.Proxies & Business
Data collection costs in 2026: what you actually payBreaks down data collection costs into four lines (proxy bandwidth, cloud egress/storage, engineering time, and failed request waste), argues cost per successful record matters more than price per GB, matches proxy type to target difficulty for cost efficiency, and gives seven tactics to cut spend without cutting output.Proxy 101
Are proxies safe? The real risks and how to choose safelyProxies are safe when the provider is paid and reputable and the proxy type matches the task, since most documented harm comes from free public proxies (a 2018 study found over a third altered traffic, with 5.15% doing so maliciously). The article gives a seven-point provider safety checklist, explains that proxies are not VPNs since most don't encrypt traffic themselves, matches proxy types (residential, static residential, datacenter, mobile) to different tasks, and covers legality and buying red flags.Proxies & Business
Data quality metrics: the 7 that matter and how to measure themDefines the seven core data quality metrics (accuracy, completeness, consistency, timeliness, validity, uniqueness, integrity) and how dimensions, metrics, and KPIs differ, explains how to calculate each one, argues most quality problems for web-collected data start at the collection layer rather than downstream, and covers turning metrics into a weighted, continuously monitored scorecard.Proxies & Business
Data extraction strategies: how to choose the right approachCovers five data extraction strategies (web scraping, API, database querying, OCR, streaming/CDC) and a source-first framework for choosing between them, plus how proxy type and session model affect reliability for web collection specifically.Proxies & Business
Data backup best practices for web data collection teamsThis guide argues scraped data needs tiered backups based on re-collection cost (not guesswork), since some data can be re-crawled while timestamped or delisted records are gone forever. It covers four asset classes (raw data, derived data, configs, job state), the importance of testing restores, and the 3-2-1 rule as a baseline, not a full strategy.Proxies & Business
The cost of poor data quality practicesPoor data quality costs a quarter of firms over $5M a year: wasted engineer hours, wrong pricing, and lost revenue. See where the money actually goes.Proxies & Business
Best web scraping practices in 2026: a developer's guideThis guide covers 2026 web scraping best practices: setting a data-driven request budget, following the consent ladder (API, Content-Signal, robots.txt, ToS, status codes), matching proxy type to the target, sending consistent request signatures, handling 429/403 responses correctly, and caching to avoid re-fetching unchanged pages.Proxies & Business
