Securonix Unified Defense SIEM
A year of hot data as standard — Securonix Unified Defense SIEM keeps 365 days searchable on a Snowflake data lake, so the investigation that reaches back eleven months is a query rather than a restore ticket.

Where data can live
BYO-AWS or BYO-Snowflake
Your own account holds the data lake, in an India region if you choose. ~450 Securonix engineers sit in Bangalore and Pune.
The hard limit
No air gap, ever
The analytics control plane is always Securonix’s cloud. BYO changes where data rests, not who operates the platform.
These are two different obligations and they lead to different vendors. “Data must stay in India” — BYO-Snowflake in an India region can answer that. “Must be air-gapped” — nothing Securonix offers answers it; see LogRhythm SIEM or Elastic Security.

Understand SIEM economics before you buy it
Most product pages skip this. We start here — so you buy a capability, not a buzzword.
What is it?
A cloud-native SIEM on a Snowflake data lake — ingestion, correlation, detection and response, with 365 days of hot searchable data included rather than sold as an upgrade.
A 90-day SIEM vs Unified Defense SIEM — the honest table
What a year of hot data and behaviour-first detection change, dimension by dimension.
| Dimension | Typical 90-day SIEM | Securonix Unified Defense SIEM |
|---|---|---|
| Retention | 90 days hot, then cold archive | 365 days hot, searchable |
| Old data | Restore ticket, then wait | Query it in the same session |
| Detection basis | Rules you wrote in advance | Baselines, and scored deviation |
| Stolen credentials | Nothing malformed to match | Behaviour is wrong, so it scores |
| New intelligence | Someone remembers to hunt | ATS sweeps history automatically |
| Data custody | Vendor's lake, always | BYO-AWS or BYO-Snowflake available |
| Honest caveat | — | No air gap; overage defaults to 120% |
| Best fit | — | Cloud-accepting, insider-risk exposed |
If your mandate requires the SIEM on your own infrastructure, weigh Exabeam LogRhythm SIEM or Elastic Security instead.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Snowflake data lake
Data is stored in Snowflake on AWS, not a proprietary index, so storage scales separately and a year of hot data is affordable. Snowflake customers can bring their own account.
Data Pipeline Manager
Collects, parses, normalises and filters telemetry before billable ingestion. Pricing is per GB/day, so these choices set the invoice — a cost control.
Analytics engine
Correlation rules run alongside UEBA behavioural models that score entities on accumulated risk — catching credential misuse that breaks no rule.
Securonix EON
EON, the cybersecurity mesh architecture, ties detection, investigation and response together with the pipeline manager — the frame, not a separate buy.
Agentic Mesh and Sam
Announced February 2026 on Amazon Bedrock AgentCore, the Mesh runs specialist agents, with Sam on Tier 1 and 2 work under human oversight. Priced on productivity, not GB.
Storage in Snowflake, analytics in Securonix’s cloud — your data can move to your own account; the control plane does not.
Twelve capabilities. Ingest, score, respond.
Unified Defense SIEM ingests into a Snowflake data lake, scores behaviour alongside rules, re-hunts history as intelligence changes, and hands analysts cases, SOAR and Sam. Here is what is inside.
Broad source coverage
Pulls telemetry from cloud, endpoint, network, identity and SaaS sources into one lake.
Pre-ingest filtering
Drops or reroutes low-value events before they count against the GB/day meter.
Common schema
Parses heterogeneous log formats into a consistent model so queries work across sources.
Bring Your Own Snowflake
Runs analytics on your existing Snowflake estate, leaving data in your account.
365 days hot
Keeps a full year immediately searchable, with no restore step before investigation.
Built-in UEBA
Baselines users and entities and scores deviation, catching valid-credential abuse.
Threat content as a service
Detection content maintained and delivered by Securonix rather than hand-built by you.
Multi-source chaining
Links related signals across sources into a single scored entity timeline.
Autonomous Threat Sweeper
Re-hunts historical data automatically as new intelligence lands.
Sam, the AI SOC Analyst
Automates Tier 1 and Tier 2 triage and investigation under human oversight.
Agentic Mesh
Coordinates specialist AI agents across detection, investigation and reporting.
Board-ready output
Produces incident and posture reporting aimed at governance audiences.

Here’s what genuinely sets Unified Defense SIEM apart — and where a self-hosted SIEM fits better.
A year of hot data changes what investigation means
Most SIEM deployments keep thirty or ninety days hot and the rest in cold storage that needs a restore job — invisible until an intrusion predates the window. Securonix keeps 365 days hot as standard, because data sits in Snowflake. Under CERT-In reporting expectations, a fast timeline makes a defensible report.
The GB/day meter is honest about what it charges for — if you read the contract
Ingestion pricing makes teams quietly drop logs. Securonix tiers ingestion and allows commitment plus pay-as-you-go. But its licensing guidelines default overage to 120% of your GB/day fee where the order form specifies no rate — buyers who leave that line blank find out in an incident month. Fix it in two lines of contract.
Six consecutive Gartner Leader placements is a durability signal
Analyst placement shouldn’t decide a purchase, but Securonix has been named a Leader in the Gartner Magic Quadrant for SIEM six consecutive times, most recently 2025, through Cisco buying Splunk and LogRhythm merging into Exabeam. That isn’t proof of fit — it’s reasonable evidence the vendor will still be there.
Behavioural detection is built in, not bolted on
Securonix began as a UEBA company and grew a SIEM around it. Instead of firing on rule matches, it scores entities on accumulated risk, so an account that logs in legitimately then touches an unfamiliar repository and moves unusual volume climbs a risk score without breaking a rule — with raw events in the same context.
The honest caveat — cloud-only, and the meter still bites
Securonix has no self-hosted or on-premises deployment: it sits on Snowflake and AWS, and Bring Your Own Snowflake changes where data rests, not where analytics run. If SaaS is ruled out, look at Exabeam LogRhythm SIEM, Elastic Security or Wazuh. GB/day bills stay predictable, not cheap, and leadership changed three times in two years.
The honest positioning
Securonix suits organisations that accept cloud SaaS, value behavioural detection and want a year of investigable history. A dictated deployment location disqualifies it outright. Against Exabeam you forgo a self-hosted option; against Sentinel, Microsoft integration; against Splunk, search flexibility. TechBag sells all of these.

Quick poll — what’s driving your evaluation?
Talk to an advisor“The full year of hot data settled it for us. We found activity from eight months prior during an investigation and never once waited on a restore.”
“The behaviour scores caught an account takeover our old SIEM had recorded and ignored. Same data, different question being asked of it.”
“Pre-negotiated overage rates meant our year-two ingestion growth was a budget conversation, not a crisis.”
“Onboarding log sources took longer than the timeline we were given. The platform is good; the implementation estimate was optimistic.”
“We ruled it out late because our regulator requires the SIEM on our own infrastructure. Nobody told us cloud-only was absolute.”
“The Data Pipeline Manager paid for the tuning effort within two quarters. We cut ingestion by a third without losing a detection.”
“Analyst standing mattered to our board. Six straight Leader placements ended a debate that had run for months.”
“Strong platform with genuine behavioural depth. It expects you to bring SOC maturity though — it will not run itself out of the box.”
Where everyone sits — the grids
Analyst firms bury this view behind paywalls, and review-site grids score satisfaction, not fit for your estate. So here’s TechBag’s synthesis of the SIEM market — tap any vendor to see why it sits where it does.

Securonix Unified Defense SIEM is one of 36 SIEM & log management products TechBag carries. The SIEM & Log Management guide narrows them to a shortlist and shows the reasoning. →
How much of your volume belongs in the cheap tiers?
Securonix meters on GB per day, and the lever you actually control is Data Pipeline Manager: one entitlement flexes across three tiers — Analytics at 1.0×, Investigation at 0.5×, Basic at 0.25×. Route firewall noise, verbose DEBUG logging and duplicated sources to the cheaper tiers and your effective capacity rises substantially. Do this classification before you sign, not during onboarding — it is much harder to renegotiate a band downward later. Illustrative rates; Securonix is quote-only.
One warning that matters more than the saving: Autonomous Threat Sweeper can only re-hunt data you actually ingested. Every source you filter out to control this bill is a source no future sweep can reach — and a blind sweep looks exactly like a clean one. Protect identity, endpoint and cloud control-plane telemetry from cost-driven filtering. Illustrative only; Securonix is quote-only.
Three ways to consume it
Securonix meters on GB per day in tiered bands, with a hybrid commitment plus pay-as-you-go. Two things decide what you actually pay, and only one is the headline rate. The first is the overage rate: Securonix’s own licensing guidelines default it to 120% of your GB/day fee where the order form specifies no rate — no vendor page tells a buyer that, and it is the commonest avoidable cost in a Securonix contract. The second is Data Pipeline Manager, which flexes one entitlement across three tiers at 1.0x, 0.5x and 0.25x. Do the classification exercise BEFORE you sign. TechBag models it and quotes in INR with GST.
GB/day band
The core meter
- Tiered bands — the per-GB rate improves as volume climbs
- Hybrid commitment plus pay-as-you-go
- NEGOTIATE THE OVERAGE: it defaults to 120% if left blank
+ Data Pipeline Manager
How you keep the meter honest
- Three tiers drawing on one entitlement: 1.0x, 0.5x, 0.25x
- Route firewall and DNS noise to Basic
- Vendor claims 30–70% effective capacity gain — model it
+ Sam, the AI SOC Analyst
The novel meter
- Billed on analyst-equivalent minutes, not GB or seats
- No other SIEM vendor prices this way
- Ask how the productivity figure is verified and audited
