Layered Security.
No Shortcuts.

We design and oversee security programs that go beyond checkbox compliance. Every layer is intentional — from DNS filtering to privileged access management to virtual CISO leadership. Security is not an add-on. It is foundational.

Every layer covered.

Endpoint Security

  • Endpoint Detection & Response (EDR)
  • Managed Detection & Response (MDR)
  • Unified Endpoint Management

Identity & Access

  • Privileged Access Management (PAM)
  • Multi-Factor Authentication (MFA) enforcement
  • Least-privilege principle enforcement

Network & DNS Security

  • DNS-layer security (Cisco Umbrella, Cloudflare Gateway)
  • Next-generation firewall management
  • Zero Trust network architecture

Email & Dark Web

  • Email security with SPF, DKIM, and DMARC
  • Dark web monitoring and credential alerting
  • Security awareness training and phishing simulations

Compliance

  • NIST CSF, CIS Controls, CMMC alignment
  • Vulnerability assessments and pen testing coordination
  • Cyber insurance readiness assessments

vCISO & Leadership

  • Virtual CISO for executive-level security guidance
  • Incident response planning and tabletop exercises
  • Security program development and roadmapping

Security is not a product.
It is a program.

Most breaches are not caused by exotic zero-day exploits. They are caused by unpatched systems, weak passwords, misconfigured email, or employees clicking phishing links. Our security programs address the boring, unglamorous fundamentals that actually prevent attacks.

We layer defense: DNS filtering stops malware before it reaches endpoints. EDR catches what slips through. Dark web monitoring alerts you when credentials are compromised. MFA limits what attackers can do with stolen passwords. Each layer assumes the others will fail sometimes — and compensates.

Common questions about Cybersecurity.

How does Leonidas deliver cybersecurity?
Leonidas operates as a cybersecurity consulting firm. We design your security program, run risk assessments, set policy, and provide vCISO leadership. For execution-layer work like EDR and MDR platform operation, 24/7 SOC monitoring, and forensic incident response, we partner with a dedicated managed security provider and manage that relationship on your behalf. This separation keeps strategy independent from execution and prevents the conflict of interest that comes from one firm both recommending and selling its own security services.
Does my small business really need cybersecurity?
Yes. Small and mid-size businesses are frequently targeted precisely because they often lack strong defenses. 43% of cyberattacks target small businesses, and ransomware does not discriminate by company size.
What is EDR and why does my business need it?
Endpoint Detection and Response (EDR) monitors devices in real time for malicious behavior and can automatically isolate compromised systems — going far beyond traditional antivirus in detecting and stopping threats.
What is a vCISO and how does it work?
A virtual Chief Information Security Officer (vCISO) provides executive-level security leadership — strategy, policy development, compliance guidance, and board-level communication — at a fraction of the cost of a full-time hire.
