AI security and agents
MCP, LLM agents in production, model supply-chain risk, GenAI browser extensions. What organisations can actually control today, what depends on the provider, and which controls to require by contract.
Technical breakdowns, practical guides and operational criteria from the Hard2bit team — the same one that runs a 24/7 SOC, handles incident response, executes pentests and supports compliance programmes at mid-market and large organisations.
We publish about the work we run every day. Every article is signed by someone who has been inside the problem, not written by an external copywriter. You'll find technical breakdowns of high-impact CVEs, implementation-focused guides on NIS2, DORA, ENS and ISO 27001, and explanations of which controls actually move maturity forward and which are theatre.
We cover five areas:
When the decision is X or Y: what each option assesses, where they overlap, and when each makes sense. Written to unblock scoping and procurement calls.
Four frameworks, one control map. What each requires and how to prioritise.
Compare →Endpoint detection, cross-domain correlation or 24/7 managed service. When to pick each.
Compare →Real cost, response capability and operational control. When to internalise, when to outsource.
Compare →What each offensive exercise validates and which one the board, auditor or regulator asks for.
Compare →When an in-house CISO makes sense and when a fractional vCISO solves the equation better.
Compare →Four areas where the blog concentrates most material. Each block links to the articles that cover the fundamentals and to the equivalent service at Hard2bit.
MCP, LLM agents in production, model supply-chain risk, GenAI browser extensions. What organisations can actually control today, what depends on the provider, and which controls to require by contract.
What each type of offensive exercise actually assesses, what a useful pentest report should deliver, and how external attack surface work differs from a compliance audit.
Live campaigns and techniques observed in real engagements. ClickFix, C2 over Microsoft Teams, Microsoft 365 account takeover, npm supply-chain attacks. Vector, indicators and the controls that actually block the technique.
Boardroom-facing material: exposure dashboards a board can act on, digital supply-chain lessons for the CISO, and continuous exposure management for regulated environments.
The blog is signed by Hard2bit's founding partners and technical team. Every article carries the byline of someone who has worked the problem in a real engagement — not an external copywriter.

How we publish, who writes, what we cover and how to cite the material.
Several articles a month. We refresh the pillar posts (NIS2, DORA, ENS, ISO 27001, pentesting, SOC, AI security) whenever the technique or the regulatory interpretation shifts.
The Hard2bit team: SOC analysts, pentesters, compliance leads and security architects. Every article is signed by someone who has worked the problem in a real engagement, not by an external copywriter.
Offensive security (pentesting, red team, external attack surface), compliance and GRC (NIS2, DORA, ENS, ISO 27001, ISO 42001, EU AI Act), AI security (agents, MCP, LLMs), defensive operations (managed SOC, MDR, threat hunting, incident response) and analysis of live cyber threats.
The technical ones are: CVE analyses, security architecture, AI, threat hunting or pentesting content is transnational. Compliance material focuses on the European regulatory frame (NIS2, DORA, EU AI Act) and on Spanish specifics (ENS). The English edition covers the same topics adapted to the UK/EU context.
