Visibility & Coverage Assessment
You cannot detect what you are not logging. We evaluate your existing monitoring capabilities, identify logging gaps and blind spots across your environment, and build a clear picture of where your detection coverage is strong and where attackers could currently operate without being seen.
Detection Engineering
We integrate your SIEM and develop detection rules built around realistic attack scenarios, not generic templates. Use-case driven detection strategies ensure your alerts are tied to actual attacker techniques, so your security team spends time investigating real threats rather than chasing false alarms.
Real-Time Threat Monitoring
We provide continuous monitoring of events and anomalies across your systems with correlation of signals from multiple sources. Rather than watching individual logs in isolation, we look for patterns that indicate attacker behavior so threats are surfaced before they cause significant damage.
Incident Response Execution
When a threat is confirmed, speed and precision matter. We execute rapid containment and eradication to stop the attack and limit damage, followed by thorough root cause analysis and impact assessment to understand exactly what happened, what was accessed, and what needs to change.
Digital Forensics & Investigation
After an incident, understanding what actually happened is critical to preventing a recurrence. We perform timeline reconstruction, evidence analysis, and attack vector identification to give you a complete and defensible account of the incident that supports both internal decisions and external obligations.
Continuous Improvement & Threat Intelligence
Attackers change their techniques. Your detection logic needs to change with them. We update detection rules based on emerging threats, integrate relevant threat intelligence feeds, and run regular reviews to ensure your monitoring capabilities stay ahead of the threats that are most relevant to your industry and environment.
AI-Powered Behavioural Detection
AI-driven attacks operate differently from human-directed ones. They move at machine speed, adapt in real time, and produce activity patterns that static rules were not designed to catch. We deploy machine learning models trained on your environment's specific baseline to identify threats that behave like normal activity until the moment they don't, including autonomous agent intrusions, AI-assisted credential abuse, and adaptive malware that modifies its behavior to evade conventional endpoint tools.
What Makes Us Different From Others
- We Understand Attacker Behavior, Not Just Indicators Threat detection built around known signatures misses novel attacks. We build detection logic around attacker techniques and behavioral patterns that hold up even when specific tools or malware change.
- Detection Engineering, Not Detection Templates Generic SIEM rules generate noise. We build detection use cases around the specific threats relevant to your industry, environment, and data, so every alert has a clear reason to exist.
- Blind Spot Elimination First Before building detection, we find the gaps. There is no point tuning alerts on systems you are not logging. We start with coverage and build from there.
- Incident Response That Is Actually Fast Response time is one of the most important factors in limiting breach damage. We execute with urgency and clear process, not escalating email chains while an attacker continues moving.
- Forensics That Hold Up Our investigations produce evidence-backed findings that can support legal, regulatory, or insurance processes if needed, not just an internal summary of what probably happened.
- Detection That Improves Over Time We treat detection as an ongoing program, not a project. Regular reviews, threat intelligence integration, and post-incident tuning keep your monitoring capabilities sharp and relevant.
- Built to Catch AI-Powered Attacks Signature-based detection was not designed for AI-driven threats that adapt in real time. Our behavioral AI models are trained on your environment's specific patterns so that autonomous agent activity, AI-assisted intrusions, and adaptive malware stand out rather than blending into background noise.
We had a SIEM deployed but no one tuning it or reviewing alerts. garrisonOne took over detection engineering, eliminated the false-positive noise burning out our IT team, and built playbooks for alert types that actually mattered. The first week they were live, they caught a credential stuffing attack we would have missed entirely.

Frequently asked questions
What is threat detection and response?
Threat detection and response is the combination of monitoring, analysis, and action used to identify malicious activity in your environment and stop it before it causes significant damage. It covers the tools, processes, and expertise needed to surface threats early, investigate them accurately, and contain them quickly.
What is a SIEM and why does it matter?
A SIEM, or Security Information and Event Management system, collects and correlates log data from across your environment to identify patterns that indicate a security threat. A well-configured SIEM is one of the most important tools for detecting threats that span multiple systems. A poorly configured one generates so many alerts that it becomes a distraction rather than a defense.
How do you make sure detection rules actually catch real threats?
We build detection use cases around known attacker techniques aligned to frameworks like MITRE ATT&CK. Each rule is tied to a realistic attack scenario, tuned to your environment, and validated to confirm it fires under the right conditions. We also test for false positives to make sure your team is not overwhelmed with noise.
How quickly can you respond to an active incident?
Response time depends on your engagement model and the nature of the incident. For organizations with an active monitoring relationship, we can begin containment actions rapidly upon confirmation of a threat. For incident response engagements, we mobilize immediately and work with your team to stop the attack and limit damage.
What happens during a digital forensics investigation?
We reconstruct the timeline of the attack, identify how the attacker gained access and what they did inside your environment, determine what data or systems were affected, and produce a documented account of events. This supports both internal decision-making and any legal, regulatory, or insurance obligations that follow an incident.
What is threat intelligence and how do you use it?
Threat intelligence is information about the tactics, techniques, and targets of active threat actors. We integrate relevant intelligence feeds into your detection logic so your monitoring is informed by what attackers are actually doing in the wild, not just what they have done historically. This is especially valuable for industries that are actively targeted.
Do we need a full SOC to benefit from threat detection services?
No. Many of our clients do not have a dedicated security operations center. We work with organizations at different levels of maturity to build detection capabilities that are appropriately scaled to their environment, team size, and risk profile. You do not need to be a large enterprise to benefit from proper threat detection.
How do detection capabilities improve over time?
Every incident, near-miss, and threat intelligence update is an opportunity to improve. We run regular reviews of detection rules, update logic based on emerging attacker techniques, and incorporate lessons learned from investigations. Detection should get sharper over time, not stay static from the day it was first deployed.
