Security Researcher & Systems Thinker
Theo H. focuses on how security operations are evolving as data, automation, and AI reshape the way teams detect and respond to threats. With a background spanning security engineering and platform design, Theo has worked on building and integrating systems that connect telemetry, detection logic, and response workflows across modern security stacks. His work has centered on improving how security teams use data — not just collecting it, but turning it into actionable context for investigations and decisions. He writes about the structural challenges in today’s security operations models, including the limits of traditional SOC architectures, the gap between automation and real-world execution, and the emerging role of AI in augmenting human analysts. His perspective focuses on what is changing — and what isn’t — as organizations attempt to move from tool-driven operations to more adaptive, system-level approaches to security.
Ask a SecOps leader whether an AI SOC analyst will replace their tier-1 team and you've asked the wrong question: a tier-1 analyst isn't a single job but a bundle of tasks, and AI has absorbed some of them while the judgment that owns the verdict stays human. I evaluate these systems task by task, not as a headcount swap.

A security organization scales when its structure matches the work it must perform, the authority it needs to act, and the coverage it can sustain, not when it adds the next box from an enterprise org chart.

I spent the last year reading mid-market CISO job specs and following what happened to the people hired against them. The specs screen for a computer science degree and a stack of certifications. The first-year board test grades almost none of it, and the gap explains a lot of the turnover.

Security tool consolidation cuts licenses, but shifts the real cost to the SOC. The hidden migration tax, like rewriting detections, retraining teams, and coverage risk, can erase the savings.

AppSec scanners generate more findings than any development team can act on. The standard response is a better aggregation platform. The response that actually works is fixing the ownership model, context injection, and feedback loop that make most AppSec findings feel like background radiation before they reach a developer's queue.

CISO burnout gets treated as a wellness problem, but the cause is structural: accountability for risks the CISO has no authority to remediate, now with personal legal exposure attached. Budget language and board trust decide how much room a leader actually has to act.

Dark web monitoring sounds like one capability but bundles three: credential monitoring, forum crawling, and actor tracking, each sourced and operated differently. Buyers conflate them, then discover they bought a credential feed when they expected adversary context.

Most CTI programs quietly collapse into IOC feed management with a weekly report attached, running one of the role's three horizons and calling it the whole function. Scope the analyst across tactical, operational, and strategic work, and judge it on whether it changes a detection or a decision inside the SOC.

A detection engineer's take on why the AI SOC demo always looks clean, and what to do about it. Theo Hartley breaks down the six incentives that make curated demos the rational default, why POC numbers don't survive contact with production data, and how to run an evaluation the vendor can't script against.

Every AI SOC vendor says the technology augments analysts. Their own ROI math says something different. Theo Hartley breaks down why "augmentation" is doing commercial work rather than describing the product — and what the broken entry-level hiring pipeline tells you about where Tier 1 is actually headed.

Explainability wins the demo. Auditability survives the audit. The three questions AI SOC buyers should add to their vendor scorecard.

Most threat intelligence never reaches a detection rule. The cause is structural: a format mismatch between TI delivery and detection workflows.

The CISO title in 2026 covers four distinct jobs: technical security, board risk translation, regulatory compliance, and AI governance.

Security culture is behavior under pressure, not a values doc. Here's how to build it from scratch before it builds itself into something you'll spend years fixing.
