Fifteen years. Same business. Same standard.

The Diamond Certification Laboratory of Australia — DCLA — is the only internationally accredited diamond grading laboratory in the country. Founded in Sydney in 2001 by the Cohen family, the laboratory is accredited by CIBJO, listed on RapNet, trusted by IDEX, and entrusted with the nation's official Diamond Masterset. Every report DCLA issues is the kind of document a court, an insurer, a jeweller, and a consumer must all be able to rely on. The sister business, The Gold Company, extends the same Cohen-family standard into the precious-metals market.

Fifteen-plus years of continuous service. whedo.it's longest-tenure relationship.

Confidentiality is not a feature of the brief; it is the brief. Lab data, client records, certification archives, and the imaging that underwrites every certificate are not material that can ever leak. Identity-first M365 architecture sits at the centre. Conditional access locks logins to managed devices and approved geographies. MFA is hardware-backed where the risk merits it. Privileged access is JIT, audit-trailed, and reviewed on cadence. Endpoint posture is enforced through Intune; anything outside policy quarantines itself before it reaches the data. Microsoft Defender XDR runs across endpoint, identity and cloud, integrated with Acronis MDR for 24/7 SOC monitoring.

Backup and recovery sit on Acronis Cyber Protect with immutable, off-site copies and rehearsed restores — because a certification business that loses its archive ceases to be a certification business. Underneath the technology is the simpler reason DCLA and The Gold Company still pick up the phone: fifteen years of the same senior practitioner inside the same environment. Three Microsoft licensing reorgs. On-prem to hybrid to cloud. The threat-model pivot from generic malware to targeted ransomware. The AI shift. DCLA has never had to relearn how IT works at their company — every transition has been folded in by the practitioner who designed the original environment.

Roy Cohen, CEO of DCLA, recorded a video testimonial that has carried across every iteration of the whedo.it site — and remains the clearest public proof point that the boutique business model holds at scale, over time, and under the kind of confidentiality pressure most engagements never see.
