Fluid Security is Now a Member of the Threat-Informed Defence Alliance!

Our mission has always been to embed cybersecurity seamlessly throughout an organisation. Today, we are proud to announce a major step forward in that mission: we have joined the Threat-Informed Defence Alliance (TIDA).

What is the Threat-Informed Defence Alliance?

The Threat-Informed Defence Alliance (TIDA), created by Arachne Digital, is a network of trusted partners committed to the systematic application of threat intelligence to improve global cyber defences.

Why Threat-Informed Defence?

For too long, the industry has relied on “compliance checkbox exercises” and generic security controls. While foundational hygiene is essential, it often fails to account for how real-world adversaries actually behave. A “Threat-Informed” approach to building defences flips the script. It moves us away from guessing and toward a strategy rooted in evidence-using actual adversary tactics, techniques, and procedures (TTPs) to dictate how we build, test, prioritise and evolve our defences.

By joining TIDA, we are aligning ourselves with a global community that speaks the language of the MITRE ATT&CK® framework. This isn’t just about collecting more data; it’s about making that data actionable.

What This Means for Our Clients

Joining TIDA directly enhances the value we bring to our partners and clients. By integrating Arachne Digital’s high-fidelity threat intelligence into our services, we have enriched our services:

• Precision-Led Strategy: We don’t just tell you to “patch your stuff”. We use TIDA-backed intelligence to identify the specific threats most relevant to your industry and region, allowing you to prioritise the security activities that directly reduce exposure to real, active threats rather than theoretical vulnerabilities alone.
• Validated Defences: Through our Adversary Emulation services, we can more accurately simulate adversary tradecraft based on real-world attacks. This ensures your security controls aren’t just “present”, but are actually effective against the methods attackers are using today.
• Measurable Resilience: This partnership allows us to help you answer questions from your board of “Are we safe?”, instead shifting the conversation to being able to demonstrate coverage of adversary tactics and techniques, with clear empirical benchmarks of their defensive maturity.

Why This Partnership Matters

Membership in TIDA reflects Fluid Security’s ongoing commitment to integrate threat-informed practices into our service delivery model, ensuring that every engagement is:

• Contextualised to specific threats relevant to the client’s industry, region, and digital footprint, enabling more precise risk assessments, threat modelling and defence planning.
• Controls are assessed for effectiveness, with defences continually refined in response to new intelligence.
• Aligned with global best practice, leveraging a recognised methodology that prioritises real adversary behaviour over theoretical models.

The Road Ahead

The cyber threat landscapes evolve rapidly, and defenders must do the same. Fluid Security joining the Threat-Informed Defence Alliance strengthens our capacity to help organisations build measurable resilience, reduce risk, respond effectively, and ultimately, build a safer digital future for our clients.

We’re not just watching the horizon for threats - we’re using them to better prioritise our defences.
