Choose Prophet or Dropzone for Mixed-Stack AI SOC Triage

If your alerts land in Microsoft Defender or CrowdStrike Falcon, start with the AI analyst your platform bundles, and buy a standalone only when alerts come from a mixed stack it cannot see. For that mixed stack, Prophet Security is the default pick because it is the only standalone vendor here with a published contract price and an optional human review of every malicious verdict. Dropzone AI is the alternative when your volume is high enough that per-investigation overages hurt. Whichever you pick, do not accept an alert-reduction number until you have run the agent beside your own analysts for 30 days and counted what it closed that it should not have.

Which AI SOC Analyst Should You Buy?

An AI SOC analyst is software that takes an alert, gathers the evidence an analyst would (process tree, sign-in history, email headers, threat intel), and returns a verdict with its reasoning, usually closing the alerts it judges benign. The decision you face is whether the version bundled with your security platform is good enough, or whether you need a vendor that reads every tool you own.

The rule that predicts regret is coverage. A bundled agent triages only the alerts its own platform generates. Microsoft's Triage Agent documentation lists the supported alert types: user-reported phish, a set of Defender for Cloud container alerts, three identity alerts, a handful of Cloud Apps OAuth alerts, and exactly one Defender for Endpoint alert ("Suspicious PowerShell command line"). That broader agent is also in Limited Public Preview, invitation only. If half your queue comes from a third-party EDR, a firewall and Okta, the bundled agent leaves half the queue untouched, however good it is at the half it sees.

So the order of operations is simple. Count where your alerts come from over the last 90 days. If more than about 70% originate in one platform, use that platform's agent first. If they are spread out, you are shopping for a standalone.

The loser in this comparison is 7AI, on published price. Its only public rate, $20 per processed alert on AWS Marketplace, is twice Prophet's $10 overage rate per investigation, and a "processed alert" is counted whenever an alert, finding or detection completes the workflow, so the meter runs on noise as well as on real incidents. An enterprise contract will be priced differently, and 7AI's platform reaches further than triage. But on the only number a buyer can see, it costs the most per unit of work.

What Does Security Copilot Actually Cost at a Real Alert Volume?

Microsoft publishes enough to build a monthly cost. The Security Copilot pricing page bills provisioned capacity at $4 per Security Compute Unit (SCU) per hour and on-demand overage at $6 per SCU. A Security Compute Unit is Microsoft's unit of compute for running Copilot prompts and agents. Provisioned SCUs bill every hour whether or not anything runs.

Microsoft 365 E5 and E7 customers get capacity included. Microsoft Learn states the allocation as 400 SCUs per month for every 1,000 paid user licenses, up to 10,000 SCUs a month. Unused SCUs reset monthly and do not roll over. Usage beyond the allocation "will be throttled at a future date," with a $6 per SCU pay-as-you-go option announced on 30 days' notice.

Microsoft does not publish an SCU cost per triaged alert. Its own billing example on the same Learn page puts an incident summary at 0.5 SCU and a prompt execution at three SCUs, so use that as a range. A practitioner writing on Microsoft's Tech Community in April 2026 warned that a triage agent processing 50 alerts in one run uses "meaningfully more" SCUs than 50 manual prompts, so plan toward the top of the range until you have measured.

The workload used for every vendor below is a 5,000-seat company sending 2,000 alerts a month to the AI analyst (24,000 a year).

Product	How it is metered	Monthly cost at 2,000 alerts
Security Copilot, E5 tenant (2,000 SCUs included)	0.5 to 3 SCU per alert (Microsoft billing example range)	$0 at 0.5 SCU/alert (1,000 SCUs used). At 3 SCU/alert, 6,000 SCUs: 4,000 over the allocation at $6 = $24,000, once overage billing switches on
Security Copilot, no E5 (provisioned)	$4 per SCU-hour, 720 hours	About $5,760 (2 SCUs provisioned) to $25,920 (9 SCUs provisioned)
Prophet Security	$50,000/year for 5,000 investigations, $10 each after	$20,000 ($240,000/year)
7AI (Security Hub listing)	$20 per processed alert	$40,000 ($480,000/year)
Dropzone AI	Sized on employees, unlimited investigations under fair use	No published price
CrowdStrike Charlotte AI	Credits; Next-Gen SIEM allotment based on ingestion	No published price

Two things change this math. First, the E5 allocation is shared across the whole tenant: Purview, Entra and Intune agents draw from the same 2,000 SCUs, so your SOC does not get all of it. Second, the marketplace listings are list prices, and marketplace deals are routinely negotiated as private offers. Treat Prophet's $50,000 as a ceiling to negotiate down from.

Microsoft Security Copilot: Who Should and Should Not Use It

Use it if you hold E5, run Defender XDR as your primary console and have Defender for Office 365 Plan 2, which the phishing workload requires. The included capacity makes the first pilot free, and the Triage Agent has the best-documented explainability in this comparison: each verdict shows a card with the incriminating evidence, a "View agent activity" step trace, and Microsoft says the agent documents its decisions, reasoning and actions "as a decision tree within Defender and records them in Microsoft Purview audit logs."

Two operational traps are documented. The agent skips any alert already resolved by an alert-tuning rule, so you must disable the built-in "Auto-Resolve - Email reported by user as malware or phish" rule or it will triage nothing. And its feedback loop, where analysts teach it your conventions, works for email and collaboration alerts only.

Do not pick it if most of your alerts come from outside Microsoft, or if you need investigation records kept beyond the session window. Microsoft's privacy documentation says session data is deleted after 180 days of inactivity. If an investigation may become evidence, export the verdict and reasoning into your SIEM or case system. For non-E5 customers that same page says data sharing with Microsoft is on by default, which your privacy team should review before go-live.

CrowdStrike Charlotte AI: Who Should and Should Not Use It

Use it if Falcon is your EDR and you want triage without another console. CrowdStrike's February 2025 launch release claims over 98% accuracy for Detection Triage. Read the footnote: accuracy there means agreement with the decisions of CrowdStrike's own Falcon Complete MDR team, which is an agreement rate with one set of humans, not an audited miss rate. The same release claims 40-plus hours saved per week, calculated as alerts triaged multiplied by an assumed five minutes each.

Check the tier before you sign. On the Charlotte Agentic SOAR pricing page, the Essentials tier "excludes Charlotte AI's Detection Triage agent and Response Agent." Only the full tier includes Detection Triage, unlimited third-party connectors and bi-directional MCP access. Pricing is credit-based with no published rate; for Next-Gen SIEM customers the credit allotment is based on data ingestion.

Do not pick it if you buy Essentials expecting the triage agent, or if your non-Falcon telemetry is large and you would have to route it into Next-Gen SIEM to get it triaged.

Prophet Security: Who Should and Should Not Use It

Prophet is the default standalone pick because a buyer can model its cost before talking to sales. The AWS Marketplace listing prices the AI SOC Analyst at $50,000 for 12 months covering 5,000 investigations, with extra investigations at $10 each, and offers "AI Watchtower," an optional 24x7 human review of malicious and inconclusive determinations, as a line item. Prophet's own site says Watchtower reviews every malicious determination with validated escalations in under 30 minutes, claims 200+ integrations, deploys single-tenant, offers bring-your-own-key, and says customer policies are "previewed, backtested, and applied."

Human review of malicious calls is useful, but notice what it does not cover. A false negative is an alert the agent closed as benign, and Watchtower, per the listing, reviews malicious and inconclusive verdicts. The benign pile is still yours to sample.

Do not pick it if your volume runs well past the 5,000 included investigations and Dropzone quotes a flat price below Prophet's per-investigation total at that volume.

Dropzone AI: Who Should and Should Not Use It

Dropzone changed its packaging in late October. A PricingSaaS change log recorded the base plan moving from a single AI SOC Analyst capped at 4,000 investigations a year per analyst to a bundle of three agents with unlimited investigations, between October 19 and 26, 2026. Dropzone's pricing page now sizes Enterprise on employees, offers "unlimited investigations under fair use" without defining the fair-use limit, and lists no prices: every tier says "Request pricing." The page also lists four agents while marking the Threat Hunter "In Beta" and the Threat Intel Analyst "Arriving 2027."

Its homepage claims 100+ integrations, no data migration and "ready in hours." It says the analyst "shows its work" and that "your analysts own every verdict."

Use it if your alert volume is high and a per-investigation meter would punish you. Do not pick it until the fair-use ceiling is written into the order form; "unlimited" with an undefined cap is a price you cannot forecast.

7AI: Who Should and Should Not Use It

7AI sells a wider platform than triage. Its homepage lists investigation, detection, response, threat hunting and a "Federated SIEM" that queries data where it lives, plus managed services. It cites a DXC Technology CISO reporting an 80% reduction in tier 1 analyst time; that is a customer testimonial, not a measured result you can check. The site also shows two different counts of alerts processed (23M+ and 14M+) on the same page.

Use it if you want one vendor for triage, hunting and services and will negotiate a platform contract. Do not pick it on the strength of the marketplace price if you have high raw alert volume: at $20 per processed alert, the 2,000-alert workload above costs $480,000 a year before negotiation. Teams that lean on SOAR playbooks rather than agents should also look at Torq SOC Brain.

How Do You Know Whether an Agent Is Closing Real Alerts?

You measure the false-negative rate yourself, because no vendor publishes one. A false negative is a real attack the agent marked benign and closed. Every vendor number above is either an agreement rate, a time-saved estimate or a testimonial.

In a Microsoft-run randomized trial of its Phishing Triage Agent with 167 analysts, analysts who could see the agent's verdicts were 29 points more likely to miss the agent's false negatives. The agent made analysts more productive and more precise, and it also made them more likely to wave through the cases where it was wrong. The paper notes its own limits: 93 emails, 11 malicious, and synthetic agent errors. When the security search company Scanner tested an LLM agent on a synthetic insider-threat case, the agent called it "Benign" and missed failed privilege escalation attempts, Lambda persistence and gigabytes of S3 exfiltration.

Gartner's research, as reported in a Prophet Security-sponsored Help Net Security article in September 2026, predicts that by 2028, 70% of large SOCs will pilot AI agents for tier 1 and tier 2 work but "only 15% will achieve measurable improvements without structured evaluation." It places AI SOC agents at the Peak of Inflated Expectations on its 2026 Hype Cycle and tells buyers to expect consolidation.

A parallel run that catches false negatives has three parts:

1. Run the agent in shadow mode for 30 days: it produces verdicts but closes nothing, your analysts work the queue as usual, and a senior analyst reviews every disagreement.
2. Seed known-bad alerts. Real attacks are rare, so 2,000 alerts may hold only a few dozen true positives, too few to estimate a miss rate. Replay confirmed incidents from the past year and have your red team generate live detections during the trial, then count how many the agent marks benign.
3. Have a human re-investigate a random 5% of agent-benign verdicts. That sample, plus the seeded attacks, is your false-negative estimate. Write the acceptable rate into the contract before autonomy is switched on.

Also test replay: give the vendor a closed alert from three months ago and ask it to re-run the investigation and show the evidence it used. An agent whose verdict you cannot reproduce cannot be defended in an incident review.

Integration Depth and Retention: What to Ask Before Signing

Integration counts (Prophet 200+, Dropzone 100+) measure breadth. For depth, ask for each tool in your stack whether the agent can only read alerts or can also query raw telemetry (EDR process trees, identity sign-in logs) during an investigation. A connector that only pulls the alert record produces shallow verdicts.

Retention is the question vendors answer least. Microsoft documents a 180-day inactivity deletion for sessions. The Prophet, Dropzone and 7AI pages reviewed for this article do not state a retention period for investigation records on their main pages. Get it in the contract: how long the evidence and reasoning are kept, where, whether they are used for model training, and in what format you get them back when you leave.

A 90-Day Plan

This Week:

1. Export 90 days of alerts by source product and compute the share each platform generates. That number decides bundled versus standalone.
2. If you hold E5, check the SCU usage dashboard in the Security Copilot portal to see how much of the monthly allocation other teams already use.

This Month:

1. Turn on the bundled agent (Triage Agent or Charlotte Detection Triage) in shadow mode, with the auto-resolve tuning rule disabled.
2. Request quotes from Prophet and Dropzone at your real annual investigation count, and ask 7AI for a platform price rather than the per-alert listing.

Before Q1 Close:

1. Complete the 30-day parallel run with seeded attacks and the 5% benign sample. Compare false-negative counts, not alert-reduction percentages.
2. Write the agreed false-negative ceiling, the fair-use definition and the retention period into whichever contract you sign.

The Bottom Line

The AI SOC analyst market has the shape of a category before consolidation: many funded startups, demos that work on curated alerts, and platform vendors bundling their own version into licences buyers already hold. Gartner tells buyers to expect consolidation, which makes vendor viability part of the purchase. Bundled agents win when your alerts live in one platform because they cost little and read that platform's data natively. Standalones win when your stack is mixed, and Prophet's published price makes it the easiest to evaluate honestly.

Run the parallel test before you believe anyone's alert-reduction number, including the one your own platform vendor quotes.
