Website security is the set of measures that protect your site — and your visitors’ data — from attacks like malware, data breaches, and downtime. Whether you run a personal blog or an online store, a few core practices stop the overwhelming majority of threats. Here’s what to defend against and how.

Why website security matters

A compromised site can leak customer data, get defaced or filled with spam, spread malware to visitors, vanish from search results, and cost you trust and revenue. And “too small to be a target” is a myth: most attacks are automated bots scanning the entire web for known weaknesses — they don’t care how popular you are. Security isn’t a one-time setup; it’s ongoing maintenance.

Most VPN problems come down to a handful of causes — a busy server, the wrong protocol, a firewall, or an out-of-date app — and most have quick fixes. This guide walks through the common issues in order, from “won’t connect” to “keeps dropping,” with the steps that actually solve them. (New to how VPNs route your traffic?

The core difference is simple: a VPN encrypts all of your device’s traffic and routes it through a secure server, while a proxy just reroutes a single app’s traffic — usually with no encryption. Both hide your IP address, but only a VPN actually protects your data. Here’s when to use each.

What is a VPN?

A VPN (Virtual Private Network) creates an encrypted tunnel between your device and a VPN server. All your internet traffic — every app and browser — travels through it, encrypted and with your IP address masked. That makes it both a privacy and a security tool. For the mechanics, see how a VPN works .

A VPN lets remote workers connect to company resources over an encrypted tunnel, so sensitive data stays private on any network — home Wi-Fi, a café, or a hotel. It’s one of the simplest, highest-impact security tools for working away from the office. Here’s how to use one well.

Why remote workers need a VPN

• Secure data transmission — a VPN encrypts the connection between your device and the company network, protecting files, messages, and credentials from interception — a core recommendation in NIST’s telework security guide . (See how a VPN works .)
• Access to internal resources — many company servers, databases, and tools are restricted to specific networks; a VPN lets you reach them securely as if you were in the office.
• Privacy on untrusted networks — it masks your IP and shields your traffic on the public Wi-Fi remote workers rely on so often.

Setting up a VPN for remote work

1. Pick the right service. If your employer provides a corporate VPN, use that — it’s configured for your company’s network. For personal protection, choose a reputable provider (criteria below).
2. Install and sign in. Download the official app for your OS (Windows, macOS, iOS, Android) from the provider’s site or app store — never a third-party mirror.
3. Configure sensibly. Enable auto-connect on startup and pick a server close to you (or the one your IT team specifies) for the best speed.

What to look for

• Strong encryption and modern protocols — AES-256 with WireGuard or IKEv2 (see VPN protocols ).
• A kill switch — blocks traffic if the VPN drops, preventing leaks (see VPN kill switch ).
• An audited no-logs policy and a privacy-friendly jurisdiction (the EFF’s guide to choosing a VPN explains why this matters).
• Enough simultaneous connections and broad device support.
