What Is the Dark Web? Risks for Businesses in 2026

The dark web is a part of the internet that isn’t indexed by search engines and can only be reached with special software such as Tor. It has legitimate uses, such as privacy and free speech, but it is also where stolen data, credentials and access to company networks are bought and sold. For businesses, the dark web matters because it is often where a breach first becomes visible. This guide explains what the dark web is, the risks it poses to businesses in 2026, and how to protect your organisation.

Surface Web, Deep Web and Dark Web

• Surface web: public websites that search engines index.
• Deep web: content behind logins or not indexed, such as email, online banking, company intranets and cloud dashboards. This is most of the internet and is entirely normal.
• Dark web: sites deliberately hidden and reachable only through anonymity networks such as Tor (“.onion” addresses) or I2P.

How the Dark Web Works

Tor routes traffic through several volunteer-run relays with layered encryption, so neither the website nor observers can easily see who is connecting. Hidden services allow sites to operate without revealing their server’s location. The same technology protects journalists, activists and people in countries with internet censorship.

Why the Dark Web Matters to Businesses

Criminal marketplaces and forums on the dark web trade in:

• Stolen credentials: usernames and passwords from breaches and from infostealer malware, often with session cookies that bypass MFA.
• Initial access: “initial access brokers” sell ready-made access to company networks, VPNs, RDP or control panels to ransomware groups.
• Leaked data: ransomware groups run leak sites where they publish data from victims who don’t pay.
• Customer data and card details used for fraud.
• Malware and attack services: ransomware-as-a-service, phishing kits and DDoS-for-hire.

Ransomware was involved in 48% of breaches in Verizon’s 2026 Data Breach Investigations Report, and many of those attacks were enabled by access or credentials traded on dark web markets. See our guide to ransomware.

Signs Your Business May Be Exposed

• Staff or customer credentials appearing in breach notification services.
• Unexpected logins, password reset requests or MFA prompts.
• Customers reporting phishing emails that use your brand and real details.
• Your company name appearing on a ransomware leak site, which usually means a serious breach has already happened.

How to Protect Your Organisation

1. Enforce MFA everywhere, preferably phishing-resistant methods such as passkeys or hardware keys for admins.
2. Use unique passwords with a password manager, and block known-breached passwords.
3. Monitor for leaked credentials: breach notification services, dark web monitoring tools and alerts for your domains.
4. Protect endpoints against infostealer malware, and shorten session lifetimes for sensitive systems.
5. Patch internet-facing systems quickly and avoid exposing RDP, SSH or admin panels to the internet.
6. Revoke access fast when staff leave or credentials leak.
7. Prepare for the worst: immutable backups and a tested incident plan. See our cyber attack recovery plan.

Is It Illegal to Access the Dark Web?

In most countries, using Tor or visiting the dark web is legal. Buying or selling illegal goods, stolen data or hacking services is not. Businesses should leave dark web investigation to specialist threat intelligence providers rather than having staff browse criminal forums, which carries legal, security and malware risks.

Frequently Asked Questions

What is the difference between the deep web and the dark web?

The deep web is anything not indexed by search engines, such as email and online banking. The dark web is a small part deliberately hidden and reachable only with tools like Tor.

How do I know if my company’s data is on the dark web?

Use breach notification and dark web monitoring services for your domains, and watch for signs such as unusual logins or targeted phishing. Security providers can run deeper threat intelligence checks.

Does MFA protect against stolen passwords?

MFA blocks most attacks using stolen passwords. However, stolen session cookies can sometimes bypass it, so endpoint protection and short session lifetimes also matter.
