Procurement decisions in event security threat intelligence are unusually consequential. The contracts are long, the prices are large, the switching costs are high, and the failure mode of a wrong call isn't "we paid too much" — it's "we missed the signal that could've prevented harm." This framework is for the security director or VP of operations who has the procurement responsibility and wants to think it through.
There are three structural options: buy a packaged enterprise platform, build internally with public APIs and engineering time, or BYOK — contract for signal sources directly and pay a thin synthesis layer to fuse them. Each is defensible in different contexts. This post is the decision tree.
The three options, defined
Buy (enterprise platform): A consolidated contract with Dataminr, Zignal Labs, Recorded Future, Everbridge, NC4, or similar. Typical pricing $25K–$150K+/yr. One invoice, one dashboard, one vendor relationship.
Build (in-house): Engineering team wires public APIs and any necessary paid signal sources, builds the fusion logic, runs the synthesis. Cost is engineering time (typically 0.5–2 FTE-years for v1, ongoing 0.25–0.5 FTE for maintenance) plus the underlying signal costs.
BYOK (bring your own keys): Contract for signal sources directly with the underlying providers (AccuWeather, Reddit, Brandwatch, Downdetector, etc.). Pay a thin synthesis layer — SignalGuard's positioning — to fuse them. Typical underlying signal cost $500–$5,000/mo plus synthesis-layer cost.
When to buy
Buy is the right answer in three contexts.
Context one: regulatory or insurance pressure for a single-vendor accountability story. Some insurance carriers and some regulatory frameworks (less common in the UK than in US enterprise contexts) prefer or require a named-vendor accountability chain. If you need a single invoice with a single SLA and a single contractually-named accountable party, buy.
Context two: zero engineering capacity, single-event-per-year cadence. If your organization is a one-event-a-year corporate offsite or a small consulting firm running scattered jobs, buy is structurally easier than BYOK. The setup cost on BYOK doesn't amortize against low scan volume.
Context three: deep existing investment in a single vendor's data model. If your security organization has trained analysts on Brandwatch's query builder for two years, replacing Brandwatch is more disruptive than upgrading Brandwatch. The right move is to keep the contract and add a thin synthesis layer (which is, structurally, the BYOK answer, but starting from a buy posture).
When to build
Build is the right answer in two narrow contexts.
Context one: extreme scale with internal engineering depth. If you're a multi-stadium operator with a CTO, a security-tech team, and 50+ events a year across 10+ venues, the engineering economics work. You'll spend $300K–$800K on the build over two years; you'll save $200K–$500K a year on enterprise contracts forever after. The break-even is roughly two years. Beyond that, build is cheaper.
Context two: signal sources your scale unlocks that vendors won't sell. A few of the highest-value signals — anonymized POS data from venue concessions, anonymized in-app behavioral data from your ticketing app, biometric throughput from gate scanners — are signals you have access to that no vendor does. If those signals are operationally material for you, only build captures them.
The risk of build is two-fold. First, calibration. Most in-house builds underweight the calibration problem (see the severity calibration post) and end up with a fusion layer that's noisier than the underlying signals. Second, maintenance. Build artifacts decay. The team that built the system rotates. The maintained internal product gets less attention than the bought-and-paid-for vendor product. By year four, most in-house builds are quietly worse than the alternative.
When to BYOK
BYOK is the right answer in the broad middle — which is most operators.
Context one: 20–200 events per year, single venue or small portfolio. The economics of BYOK assume enough volume to amortize the setup cost (~10–20 hours of integration time across the relevant providers) and enough scan velocity to extract value from the synthesis layer. 20+ events a year is roughly the threshold.
Context two: existing partial contracts you don't want to throw out. If you already have AccuWeather, or Brandwatch, or Broadcastify Premium, or HERE Traffic — keep them. BYOK lets you keep what you have and add what you don't. Buy forces you to consolidate, which is the wrong direction.
Context three: multi-pillar coverage matters more than single-pillar depth. If your operation needs equally good chatter + environment + movement + context, BYOK gives you best-of-breed in each pillar without a single-vendor's coverage gaps. If you only need deep dark-web chatter and nothing else, buy a dark-web specialist (see the dark-web buyer's guide).
Context four: budget constraints between $10K/yr and $60K/yr. This is the band where buy is too expensive (no enterprise contract fits cleanly under $30K) and build is too expensive (engineering FTE-years cost more than that). BYOK is the only structurally-coherent answer in the middle band.
The decision tree, compressed
Single-event-a-year, no infrastructure?
→ BUY (small vendor)
→ Or: SignalGuard PAYG ($19/scan)
20+ events/year, multi-vendor existing contracts?
→ BYOK
→ SignalGuard Pro/Team tier + BYOK on /integrations
Multi-stadium, 50+ events/year, internal eng team?
→ BUILD (long-term)
→ Or: BYOK with full custom signal sources
Enterprise-mandated single-vendor accountability?
→ BUY (Dataminr, Recorded Future, Everbridge)
Need single-pillar depth (e.g., dark-web specialist)?
→ BUY specialist (DarkOwl, Cybersixgill, etc.)
Budget $10K–$60K/yr?
→ BYOK (no other option fits)
What we'd ask a vendor in a procurement call
Independent of which path you take, the questions worth asking any threat-intel vendor:
- What's your false-positive rate at the action threshold over the last 90 days? (Calibrated answer = good vendor. "We don't measure that" = walk away.)
- What does your data model look like if I keep my existing AccuWeather contract? (Real BYOK support vs marketing-BYOK.)
- What's the contractual exit ramp? (Auto-renewal, notice period, data export.)
- What's the audit-trail surface? (Critical for any regulated context — see the Code of Practice post.)
- What's the calibration drift policy? (How do they detect their own model drifting and recalibrate.)
A vendor that answers all five well is rare and worth working with. A vendor that answers three of five honestly is the realistic best case. A vendor that won't answer is the easy walk-away.
The honest SignalGuard pitch
We're a BYOK synthesis layer. We're the right answer for the broad middle — operators with 20–200 events a year, multi-vendor existing contracts, $10K–$60K/yr budgets, and an operational need for cross-pillar fusion. We're not the right answer if you're a single-event-a-year consultancy (use our PAYG tier and skip the BYOK setup) and we're not the right answer if you're a multi-stadium operator with a CTO who's already evaluating build (in which case, build — and call us in year four when you're tired of maintaining it).
The fastest way to test fit is to run a free scan at /scan on a venue you operate, with no keys wired. If the baseline brief tells you something useful, the BYOK upgrade path on /integrations is straightforward. If the baseline brief tells you nothing — which is honestly possible for some operator profiles — we're not your fit, and you've saved a procurement cycle.
