We're finalizing a multi-year SOC overhaul for a large hospital network. Compliance (HIPAA, etc.) is non-negotiable, but so is actual detection efficacy and operational cost. Our shortlist is down to Google Chronicle and Securonix.
I need real-world feedback on these two, specifically for a healthcare context. Forget generic "AI/ML" marketing sheets. I'm talking about:
* **Pricing models:** Chronicle's ingestion-based model vs. Securonix's more traditional user/EPP models. What did your actual 3-year TCO look like, including professional services for deployment? Be specific about data volume if possible.
* **Detection content:** Out-of-the-box rules for healthcare-specific threats (insider access abuse, patient data exfiltration, medical device anomalies). Which platform required less customization to be effective?
* **Operational overhead:** Chronicle's YARA-L is powerful, but what's the learning curve for an existing SOC team? Securonix's UEBA claims are strong—does it actually reduce alert fatigue in a clinical environment?
* **Contract pitfalls:** Any gotchas in the Google or Securonix agreements? Specific clauses around data ownership, breach of PHI responsibilities, or support SLAs that needed heavy negotiation?
Our preliminary analysis shows Chronicle could be 15-20% cheaper at our projected ~80 TB/day, but only if we accept their standard support terms. Securonix is pushing their bundled MDR offering hard, which complicates the cost comparison.
Who has actually implemented one or both in a comparable environment? What were the hard lessons?
List price is for suckers
