Cybersecurity Services

Security threats do not target organizations based on size or industry. They target organizations that have gaps. We deliver the full range of cybersecurity services your business needs to find those gaps before an attacker does, protect what matters most, and respond effectively when incidents occur. Whether you need a focused assessment, continuous monitoring, or ongoing security operations support, we work as a direct extension of your team.

Security Assessment & Audit

Comprehensive, risk-driven security assessments that go beyond surface-level audits. We evaluate your architecture, controls, and configurations against leading frameworks like NIST CSF, ISO 27001, and CIS Benchmarks.

Learn More

Vulnerability Assessment

Continuous visibility into your attack surface through automated intelligence and expert validation. We eliminate noise and focus on exploitable risks that actually matter to your business.

Learn More

Penetration Testing

Advanced, manual penetration testing that emulates real-world adversaries. Our engagements go beyond automated scanning to uncover deep technical and business logic vulnerabilities before attackers do.

Learn More

Endpoint Security

Endpoints are often the weakest link in your security chain. We transform them into controlled, monitored, and resilient assets through hardening, EDR deployment, and continuous threat detection.

Learn More

Network Security

We secure your network as a controlled environment, not an open battlefield. From firewall reviews to adversarial simulations, we identify and eliminate the paths attackers use to move inside your infrastructure.

Learn More

Threat Detection & Response

Modern threats don't knock. They blend in. We build detection capabilities that catch attackers early, respond fast, and continuously improve based on evolving attacker behavior patterns.

Learn More

AI Security

AI is being used to attack organizations at a scale and speed that traditional security tools were not designed to handle. We help you understand your AI threat exposure, test your defenses against AI-powered attack techniques, and deploy AI-enhanced detection that matches the sophistication of the threats targeting you.

What Makes Us Different From Others

Attacker Mindset, Defender Execution We think like the adversary and build defenses that hold up under real-world attack conditions. That perspective shapes everything from how we scope assessments to how we validate that remediation has actually closed the right gaps.
Manual Expertise Over Automation Automated tools miss what skilled analysts catch. Our work combines both, with human judgment driving every conclusion rather than letting scanner output stand on its own.
Risk-Prioritized, Not Checkbox Driven Every finding is tied to real business impact. We do not bury your team in theoretical vulnerabilities that pose no genuine risk to your specific environment.
Framework-Aligned from Day One Our work maps directly to NIST CSF, ISO 27001, CIS Benchmarks, and industry-specific compliance requirements. Findings are useful not just for your security team but for your auditors and compliance programs as well.
Full Lifecycle Coverage From initial assessment through remediation, retesting, and ongoing monitoring, we stay engaged beyond the report. Security improvements only count when they are actually implemented and verified.
Clear Communication at Every Level Technical teams get actionable findings with specific remediation steps. Executives get business context and risk framing they can use to make decisions. No jargon, no translation required.

We had no formal security program when we engaged garrisonOne. Twelve months later we have a fully documented security posture, passed our first SOC 2 Type II audit, and have 24/7 SOC monitoring running. They handled everything from initial risk assessment through audit support. Genuinely transformative.

Frequently asked questions

What is cybersecurity and why does my business need it?

Cybersecurity is the practice of protecting your systems, networks, data, and people from digital attacks, unauthorized access, and damage. Every business that uses technology is a potential target. Strong cybersecurity reduces the risk of breaches, protects customer data, and keeps your operations running without costly interruptions.

What types of cybersecurity services does garrisonOne provide?

We cover the full spectrum of cybersecurity: security assessments and audits, vulnerability assessments, penetration testing, endpoint security, network security, and threat detection and response. Whether you need a one-time audit or an ongoing security partnership, we can help.

How do I know which cybersecurity service is right for us?

It starts with understanding your current security posture and your biggest risks. We typically recommend beginning with a security assessment to identify gaps, then building a prioritized plan from there. Our team works with you to match services to your environment, industry, and budget.

What is the difference between a vulnerability assessment and a penetration test?

A vulnerability assessment identifies and prioritizes known weaknesses across your environment. A penetration test goes further: a skilled tester actively tries to exploit those weaknesses to demonstrate real-world impact. Both are valuable, and many organizations benefit from doing both together.

How often should we conduct security assessments?

At a minimum, once a year. However, organizations undergoing significant changes, such as new infrastructure, cloud migrations, or mergers, should assess more frequently. We also recommend continuous vulnerability management to maintain visibility between formal assessments.

Do you work with small and mid-sized businesses or only large enterprises?

We work with organizations of all sizes. Cyber threats don't discriminate based on company size, and neither do we. Our services and engagement models are scoped to fit your organization's scale and risk profile.

Can you help us meet compliance requirements like ISO 27001, PCI-DSS, or GDPR?

Yes. Our security assessments and advisory services are designed to align with major compliance frameworks. We help you understand where you stand against specific requirements and what needs to change to meet them.

What happens after you find vulnerabilities or security gaps?

We provide a detailed remediation roadmap with prioritized steps based on risk and business impact. Our team stays engaged to answer questions, guide your team through fixes, and retest to confirm issues have been resolved properly.
