How Leonidas Protects Your Business: Our Security Approach

The Leonidas approach to cybersecurity rests on a simple observation: most breaches don't happen because the attacker was brilliant. They happen because something basic was missing — an unpatched server, a credential that was reused across personal and work accounts, a backup that hadn't been tested, a vendor with broader access than they needed. Our methodology is structured around making sure those basics are in place, then layering more sophisticated controls on top. It's organized as four phases — assess, protect, monitor, respond — that work together as a cycle rather than a one-time project.

Phase 1: Assess

Every security engagement at Leonidas starts with an assessment, because you can't protect what you haven't mapped. The assessment looks at five things: what data the business actually holds and what its sensitivity classification is, who and what has access to that data, what controls are currently in place and how they're enforced, where the gaps are between current state and the business's compliance or threat-model requirements, and what would actually happen during a realistic attack scenario.

That last piece is what separates a useful assessment from a checkbox exercise. We don't just ask whether MFA is enabled; we ask what happens if a specific user's MFA device is compromised. The answers tend to surface gaps that a control inventory misses.

Phase 2: Protect

Protection is where most of the budget tends to live, and where the temptation to overbuy is highest. Our framing for protect is to insist on coverage of the core control categories before optimizing any one of them:

• Identity — strong MFA on every account, conditional access policies that limit high-risk sign-ins, privileged access management for admin credentials
• Endpoints — modern EDR or MDR coverage on every device, current patches, full-disk encryption, application allow-listing where feasible
• Network — segmentation between user, server, and guest traffic, properly configured firewall rules, DNS-layer filtering
• Data — encryption in transit and at rest, classification labels on sensitive data, DLP controls calibrated to the business's actual risk profile
• Backup and recovery — immutable backups that ransomware can't reach, regularly tested restoration procedures, documented recovery time objectives

Coverage matters more than depth. A business with adequate controls in all five categories is more resilient than one with elite controls in two and gaps in three.

Phase 3: Monitor

Controls without monitoring are static defenses against an active adversary. The monitoring layer is what gives security teams visibility into what's actually happening: who logged in from where, which endpoints are exhibiting suspicious behavior, which alerts represent real incidents versus noise. For mid-market clients, this typically means a managed SOC service that combines log aggregation, threat detection rules, and human analyst review. For smaller businesses, it means a tighter scope focused on the highest-value telemetry — identity events, endpoint detections, and outbound network anomalies.

Phase 4: Respond

The respond phase is the test of everything before it. When an incident happens, the question isn't whether the technology will perform — it's whether the people, runbooks, and communication paths are in place to act on what the technology is reporting. We work with clients on incident response plans that include who gets called when, what gets isolated immediately, what gets preserved for forensics, how customers and regulators are notified, and what the criteria are for restoring service. The plan gets tested in tabletop exercises so the first time it runs isn't during the actual incident.

This four-phase approach isn't unique to Leonidas — it maps to NIST CSF and similar frameworks — but how it's executed at SMB scale, with limited budgets and lean teams, is what differentiates regional MSSPs. If you're evaluating your current security posture, a free assessment typically takes 30 minutes and produces a concrete view of where the next dollar of security spend has the highest return.
