Cryptography is the last line of defence
When an attacker gets through your network controls, bypasses your endpoint protection, and compromises a privileged account — what stops them from reading, exfiltrating, or manipulating your most sensitive data? For most organisations, the honest answer is: not much.
Data-centric security changes that calculus. By protecting data at the cryptographic layer — through strong PKI, rigorous certificate lifecycle management, hardware-backed key storage, and data loss prevention — organisations ensure that data remains protected even when the systems around it are not. Nomios delivers the expertise to build and operate that foundation.
Why cryptographic infrastructure is hard to get right
Cryptography is powerful — but only when it is correctly designed, properly implemented, and actively maintained. Most organisations underestimate the operational complexity.
Certificate sprawl
- Organisations typically have thousands of certificates across their environment — many untracked, some expired, others misconfigured. Each one is a potential outage or security gap.
Key management complexity
- Encryption is only as strong as the protection of the keys. Without proper key management infrastructure, cryptographic controls provide a false sense of security.
The quantum threat
- Quantum computing will render current asymmetric cryptography obsolete. Organisations that are not preparing for cryptographic agility today face a future where their historical encrypted data is at risk.
Regulatory obligations
- NIS2, DORA, GDPR, and eIDAS all impose requirements around encryption, key management, and cryptographic standards — with increasing specificity about what is and is not acceptable.
Operational blind spots
- Many organisations do not know what data they hold, where it lives, or how sensitive it is. Without that visibility, data protection controls cannot be applied where they are needed most.
Shadow PKI & rogue certificates
- Development teams, cloud workloads, and third-party integrations generate certificates outside of centralised control — creating trust chains that are invisible to security teams.
Four specialist disciplines
Each addressing a distinct layer of data-centric security — from cryptographic infrastructure to data loss prevention and quantum readiness.
Public Key Infrastructure
PKI is the foundation of digital trust — and digital sovereignty. Nomios helps organisations design, deploy, and operate the cryptographic infrastructure that puts them in full control of who can access and read their most sensitive data.
CLM Certificate Lifecycle Management
Unmanaged certificates are one of the most common — and most preventable — causes of outages and security incidents. Nomios helps organisations achieve complete visibility and automated control over every certificate in their environment, from any CA.
HSM Hardware Security Module
Software-based key storage is a single vulnerability away from total cryptographic compromise. HSMs provide the tamper-resistant, certified hardware environment that keeps your most critical keys safe — no matter what happens to the systems around them.
Deep cryptographic expertise — operationally delivered
Cryptographic depth, not just tooling
- Our Data Security practice is built on genuine cryptographic expertise — architects and engineers who understand the mathematics, the standards, and the operational realities of running cryptographic infrastructure at scale.
Full lifecycle from strategy to operations
- We design the architecture, deploy the platforms, and operate the infrastructure — one partner across the full lifecycle, without knowledge loss between phases.
Quantum-ready thinking built in
- Every cryptographic architecture we design today is evaluated for post-quantum readiness — ensuring the infrastructure you build now can be migrated without a complete rebuild.
Connected to the broader security programme
- Data security does not operate in isolation — it connects to identity (PKI and certificates), network security (TLS inspection), and compliance. Our cross-domain expertise ensures it all fits together.
How well protected is your data — really?
Most organisations discover their cryptographic gaps at the worst possible moment. Talk to our team about a data security assessment before that happens.
