Precision MDR Beyond Correlation

Deepwatch vs. ReliaQuest

As MDR models evolve, organizations looking to reduce security operations at scale are faced with a complex choice: is alert-first MDR enough when every new detection creates more downstream decisions, noise, and analyst burden?

ReliaQuest has built a trusted platform that aligns with modern SOC requirements and broad tool compatibility. Deepwatch was built for teams that have reached the next inflection point: where success is no longer measured by alert quality, but by how much decision friction can be removed before response even begins.

What Separates Deepwatch and ReliaQuest

Both Deepwatch and ReliaQuest aim to help security teams manage complexity. Both operate across heterogeneous environments. Both offer 24/7 coverage and experienced analysts.

The difference isn't coverage, it's how decisions are made.

ReliaQuest focuses on producing broad, MITRE-aligned detection coverage upfront, then correlating telemetry during the investigation phase after alerts have already been generated.

Deepwatch is designed to decide which alerts should exist at all.

That distinction becomes critical as environments scale and security teams are asked to prove not just activity, but measurable risk reduction.

The Real Difference is the MDR Model

Many modern MDR and XDR platforms, including ReliaQuest, operate in a high-volume, alert-first detection model:

  • Alerts are generated by SIEMs, EDRs, and cloud tools, often using custom detection content authored and deployed by ReliaQuest via GreyMatter.
  • Detection logic prioritizes broad MITRE coverage, then producing large volumes of single-source detections.
  • Analysts investigate and prioritize after alerts are grouped, which improves organization and investigation efficiency but does not reduce the number of decisions teams must make.

Deepwatch Operates Differently.

Precision MDR is risk-first, not alert-first, meaning detection decisions are driven by an always-on understanding of the business: users, assets, identities, and exposures before alerts are created, rather than reconstructing context after they fire.

With Deepwatch:

  • Raw signals are evaluated before alerts fire.
  • Detections are scored using risk, exposure, and context.
  • Only high-risk detections are prioritized for analyst action.

This shift from correlation to risk decisioning is what separates Precision MDR from correlation-heavy MDR platforms.

Where Reliaquest Works Well and Where It Breaks Down

Where Reliaquest works well:

  • Broad MITRE-aligned detection coverage.
  • Rapid ingestion of alerts across many tools.
  • Investigation workflows that consolidate telemetry into a single pane of glass.
  • Scalable automation for handling large detection volumes.

Where teams begin to feel friction:

  • Alert volume still scales with environment growth.
  • Correlation organizes noise but does not eliminate it.
  • Risk context is applied late in the workflow, after detections are already created.
  • A large portion of triage and disposition is handled by automation and agentic AI, with many detections never reviewed by a human.
  • Decision quality can vary as risk is inferred downstream rather than determined upfront.

For many teams, this results in a well-organized SOC that is still over-alerted, spending more time managing noise than reducing risk.

Why Precision MDR Changes the Outcome

Deepwatch was built to address the limits of correlation-heavy MDR.

Precision MDR replaces alert-driven MDR with risk-first detection, powered by a dedicated detection engine (DRS) and a continuously maintained, risk-scored inventory of the business.

Deepwatch maintains a live, risk-scored view of users, assets, identities, and cloud resources so detections are evaluated with business context before alerts exist, not reconstructed afterward.

As a result:

  • Noise is suppressed upstream using real business and exposure risk.
  • Analysts work a short, prioritized queue tied to impact.
  • Active response is driven by risk, not alert volume.

This enables Precision MDR to deliver dramatically higher signal-to-noise ratios while keeping humans accountable for the decisions that matter most.
