02 Services
Eight core disciplines that work together, so your systems are tested, hardened, monitored and defended end to end by one team.
Vulnerability assessments and penetration tests that find your weaknesses the way an attacker would — before one does.
Firewalls, segmentation and intrusion prevention that keep attackers out — and contain them if they get in.
Encryption at rest, in transit and in use, with managed keys and compliance-ready standards.
MFA, least privilege and privileged-access controls so only the right people reach the right systems.
CIS-based hardening, drift detection and attack-surface reduction across servers, endpoints and network devices.
24/7 SIEM-based detection mapped to MITRE ATT&CK, with investigation and response when alerts fire.
Rapid, expert-led response that contains active threats, finds the root cause and restores operations.
Immutable, tested backups and recovery plans that get you operational fast after ransomware or failure.
03 How we work
Every engagement follows the same disciplined cycle — so you always know what we're doing, why, and what comes next.
We map your environment and test it the way an attacker would, through vulnerability assessments, configuration reviews and penetration testing.
Penetration testingWe close the gaps that matter most first — segmentation, encryption, identity controls and secure configuration baselines.
Hardening servicesSIEM-based monitoring watches your systems around the clock, with detection rules mapped to MITRE ATT&CK.
Security monitoringWhen something happens, we investigate, contain the threat and restore operations from tested backups.
Incident response04 Case studies

05 Why Grey
Clear communication, honest pricing and accountability for the result — the things that matter long after the contract is signed.
You get a clear, upfront quote for every engagement — no hidden fees and no surprise add-ons at renewal.
We stand behind every deployment. If your security posture doesn't meet the standard we agreed on, we fix it — no exceptions.
No off-the-shelf bundles. Controls are designed around how your team actually works, so protection runs quietly in the background.
Our work aligns with frameworks such as ISO 27001, SOC 2, PCI DSS and PIPEDA, so you're prepared when auditors and customers ask.
