The new ROI for dark web monitoring

Article originally published on Fast Company in December 2025.

For years, the dark web felt like an abstract danger, something for security teams to whisper about during board briefings. Today, it is an active marketplace where basic identity data trades for pocket change while verified financial accounts fetch hundreds or thousands of dollars. Recent price indexes show U.S. Social Security numbers selling for as little as $1 to $6, while online bank logins and verified exchange accounts command far higher sums. 

That market reality matters because attackers buy, combine, and weaponize that data quickly. A leaked record creates an opportunity: phishing, account takeover, SIM swap, or credential stuffing can follow in days. The FBI’s IC3 reported billions in losses last year, making clear that exposure translates into real financial harm, not just reputation noise. 

MAKE MONITORING MEAN SOMETHING 

The chief information security officer or chief risk officer, backed by the CEO, should bring this request to the CFO and board—framed as a financial control rather than a technical product. Boards fund measurable outcomes, not fear, so convert detection into dollars avoided by treating monitoring, triage, and cleanup as three linked stages. 

Monitoring involves continuously scanning feeds, forums, paste sites, and broker lists to establish your baseline exposure. Triage is the human validation and prioritization step that decides which alerts need immediate action, and assigns remediation owners. Cleanup is the takedown and suppression work—broker negotiations, platform removals, carrier locks, and SEO/PR suppression—that actually reduces visible records.  

Start with four metrics that map to those stages: exposure delta measured after cleanup, mean time to purge measured from validated detection to verified removal, dwell-reduction as the modeled shrinkage in an attacker’s window after triage and cleanup, and response cost avoidance as the dollar value of prevented escalations. 

TELL THE CFO A STORY IN DOLLARS 

Translate percentages into dollars. For example, if an initial scan finds 1,000 exposed records and you model each at $120 of actionable risk, raw exposure equals $120,000. Reducing visible exposure by 40% therefore protects $48,000 directly, before accounting for reputation and continuity effects. 

Make the dashboard compact: Show baseline and mitigated scenarios side by side with conservative assumptions, and present the four mentioned KPIs together. Emphasize mean time to purge as the primary operational lever, because shortening the window between validated detection and verified removal typically drives improvements in the other metrics and is closely correlated with lower breach costs, as IBM’s Cost of a Data Breach shows. Boards respond to timelines as much as they do to totals. 

A 90-DAY SPRINT THAT PROVES VALUE 

Think of this 90-day sprint like cleaning and locking your house after a break-in: First you take an inventory so you know what’s missing or exposed, then you fix the obvious doors and windows, and finally you set up routines so the house stays secure. 

In the first seven days, you map everything that’s visible online—accounts, email addresses, leaked files—so you have a clear starting point. Over the 21 days, focus on fast, high-impact fixes: Strengthen passwords and authentication, ask carriers to apply extra protections, and ask platforms or brokers to remove the most dangerous listings. 

In days 30-60, continue removals and start recovery tasks that take longer, like negotiating with data brokers or suppressing search results. In days 61-90, automate the handoffs so future alerts immediately trigger legal, technical, or PR steps. And then you measure concrete results—how many items were removed and how many days it took to remove them—so the effort shows up in dollars saved, not just alerts. 

At LeyesX we use this approach to produce early exposure delta and mean time to purge baselines. In practice, those first 90 days are when monitoring shows its value on a ledger instead of a report. 

DON’T CONFUSE MONITORING WITH THEATER 

When you evaluate vendors ask for two simple performance numbers and have them explained in plain terms: mean time to detect, which is how quickly they spot a new exposure after it appears online, and mean time to respond, which is how long it takes from that detection to a verified remediation. Also ask them to prove what they actually watch. “Source coverage” means a clear list of where they search for leaks—for example, data-broker listings, paste sites, underground marketplaces, Telegram channels, and other forums where stolen or leaked records are traded—not vague claims about “the dark web.” 

Finally, the best providers show how detection turns into action: A real ROI vendor will not only send an alert but also have playbooks and relationships that let them push for carrier locks, file legal takedowns, and coordinate PR or SEO suppression so an alert becomes a removal or a mitigation, not a report that sits unread. 

Many companies buy monitoring because it feels responsible. The difference between theater and defense is the ability to act. Monitoring without enforcement creates noise. Real ROI arrives when monitoring, telecom partners, legal takedowns, and narrative control work in concert. 

The stakes are real. IBM’s report found average breach costs in the millions, driven by lost business, downtime, and recovery expenses. Faster detection and removal of exposed data reduce disruption and downstream costs, which is precisely what targeted monitoring and coordinated takedowns aim to deliver. 

MAKE EXPOSURE A FINANCIAL INSTRUMENT 

Treat exposure as a line item on your risk ledger. Report the compact dashboard monthly, model avoided losses, and tie renewal to KPI improvements. When boards see measurable drops in exposure and faster purge times converted into dollars avoided, monitoring stops being a cost of paranoia and becomes a measurable risk control. 

Start small and measure aggressively. Propose a 90-day pilot to your CFO. If the numbers move, the budget will follow.
