Replacing Legacy SIEM with Google SecOps at a Regional Finance Provider

About the Customer

A regional finance provider offering loans, leasing and savings products through a mix of branches and digital channels. The company manages sensitive customer and transaction data, operates under tight regulatory oversight, and must provide board-level assurance that cyber risk is being actively managed.

Starting Point: Outgrowing a Legacy Monitoring Stack

The organisation had accumulated multiple point tools for logging and monitoring over the years. As the environment grew more hybrid and API-driven, several pain points emerged:

• Logs scattered across different systems with limited correlation
• No single “source of truth” for security events
• Analysts spending time chasing false positives instead of investigating real issues
• Difficulty producing clear, audit-ready evidence for regulators and internal audit

Leadership wanted to move away from ad-hoc monitoring and adopt a next-generation SecOps platform that could support the next 5–7 years of growth.

Why Google SecOps Won the Evaluation

Scybers was engaged as the managed security provider and asked to help evaluate next-gen SIEM options. During a structured evaluation, Google SecOps stood out because it offered:

• A cloud-native analytics engine capable of handling current and future log volumes
• Built-in Google and Mandiant intelligence tuned for financial-sector threats
• Integrated SOAR to standardise and automate response workflows
• A simple, scalable model that wouldn’t demand a large internal SOC to operate

On the back of this evaluation, Google SecOps was selected as the core platform for the new security operations model.

The Scybers Implementation: From Design to 24/7 Operations

Scybers led the end-to-end rollout:

Design and Build

• Defined the SecOps reference architecture, log onboarding priorities and use-case catalogue
• Implemented Google SecOps (Chronicle SIEM + SOAR) as the central analytics and response layer
• Onboarded critical logs from infrastructure, applications, identity, and network controls

Intelligence and Detections

• Enabled GCTI and Mandiant curated rules relevant to financial services
• Added Scybers’ own detection content for fraud attempts, policy abuse and suspicious user activity

Playbooks and Governance

• Codified incident playbooks that matched the bank’s internal policies (who to notify, when, and how)
• Established joint governance routines: weekly tuning sessions and monthly risk/incident reviews with IT leadership

Managed Operations

• Scybers’ 24/7 team took responsibility for monitoring, triage, investigation and guided response, with clear escalation paths into the customer’s IT and risk teams.

The Impact: From Fragmented Logs to a Living Security Nerve Centre

Within weeks of going live, the new model changed how security was managed day to day:

• Analysts no longer jumped between tools; Google SecOps became the single pane of glass for security events
• Time to understand and act on an incident dropped sharply, thanks to correlated timelines and automated enrichment
• Previously unseen patterns (e.g. slow-burn account misuse, unusual access to finance systems) were surfaced early
• The IT leadership team received concise, data-backed summaries of incidents and trends, which fed directly into risk committee discussions
• For audits and regulatory reviews, the organisation could now show complete event trails and standardised incident workflows, improving confidence with external stakeholders

As the CIO put it, Google SecOps plus Scybers turned security operations from “reacting to tickets” into “running a continuous, data-driven risk function.”

About Scybers’ Role

Scybers combines:

• Deep experience in designing and operating Google SecOps
• A 24/7 managed SOC delivering triage, investigation and response
• BFSI-specific detection content and governance practices
• CISO-level advisory to align operations with board and regulator expectations

This is further enhanced by Scyra, Scybers’ agentic service layer that automates routine investigations and standardises workflows, allowing the customer’s own team to operate more confidently on top of Google SecOps.

Together, Scybers and Google SecOps gave the finance provider a modern, scalable security operations capability without having to build a large in-house SOC from scratch.
