Services

Focused help where normal support stops.

I work across cybersecurity and the underlying IT systems security depends on. Engagements can be advisory, investigative, or hands-on remote troubleshooting.

01

Cybersecurity consulting

Practical security reviews for small organizations that need to understand exposure, priorities, and next steps without enterprise-scale overhead.

  • Security posture and risk review
  • Account, endpoint, and access hardening
  • Security control recommendations
  • Incident triage and second opinions
02

Microsoft 365 & identity

Security-focused help with the cloud accounts, permissions, and collaboration tools many small businesses depend on every day.

  • MFA and account security
  • Permissions and access review
  • Exchange, Outlook, and Teams issues
  • Tenant cleanup and configuration guidance
03

Networks & remote access

Troubleshooting beyond the basic ISP handoff when the real problem is inside the network, VPN, DNS, routing, or endpoint configuration.

  • VPN and remote-access troubleshooting
  • DNS, DHCP, and connectivity issues
  • Wi-Fi and network configuration
  • Router, firewall, and segmentation review
04

Technical escalation

For the issues that have already bounced between vendors, Tier 1 support, or internal staff and still are not resolved.

  • Windows and endpoint troubleshooting
  • Printer and business application issues
  • Software configuration and compatibility
  • Vendor-support escalation and diagnosis

How I work

Direct access to the person solving the problem.

No call-center maze. No generic script pretending every problem is the same. The engagement starts by defining what is actually broken, what is at risk, and what access is truly required.

1

Scope

Clarify the problem, affected users or systems, business impact, and the desired outcome.

2

Secure access

Use the minimum access necessary for the work and avoid unnecessary credential exposure.

3

Diagnose & resolve

Work from evidence, test changes, and explain material risks before making consequential changes.

4

Close the loop

Confirm the outcome and leave you with a clear summary of what was found, what changed, and what should happen next.

Security by default

Access is temporary. Trust is earned.

Cybersecurity consulting only works when the consultant treats access as a liability, not a privilege. Remote work should be scoped, authorized, auditable where possible, and removed when the engagement ends.

About

Tristian Cockerel

Independent Cybersecurity & IT Consultant

My focus is practical cybersecurity: understanding how systems are actually used, where access and configuration create risk, and how to fix problems without adding unnecessary complexity.

I also handle the networking, Windows, Microsoft 365, printer, VPN, and endpoint issues that frequently sit underneath security problems or fall between traditional vendor-support boundaries.

Request a consultation

Tell me what is happening.

Describe the issue, what systems are involved, and how it is affecting the business. I will use that information to determine whether the engagement is a fit and what the next step should be.
