DFIR · M365 Security · SOCaaS Handoff

Built for businesses where one compromised account becomes a real incident.

Black Tower Cyber serves organizations that rely on Microsoft 365, handle sensitive client data, and need practical incident response, tenant hardening, and security readiness without hiring a full internal security team.

Ideal Client Profile
High-risk, lean teams
10–100 employees

Enough complexity to be targeted, not enough staff to run security alone.

M365 and email-dependent

Email, files, identity, and money movement run through cloud accounts.

Needs answers, not noise

Incident response, cleanup, readiness, and a clear path into monitoring.

Best Fit

  • Businesses using Microsoft 365, Entra ID, Exchange Online, SharePoint, or OneDrive.
  • Firms with sensitive client data, financial transactions, or regulatory pressure.
  • Teams that already have IT support but need security response, investigation, and hardening.
  • Companies that want to clean up the tenant before moving into ongoing monitoring.

Not the Right Fit

  • Businesses looking for general helpdesk, printer support, workstation setup, or basic IT outsourcing.
  • Companies that want unlimited incident response included in a low-cost monthly plan.
  • Environments unwilling to enforce MFA, clean up risky apps, or address known security gaps.
  • Organizations looking for checkbox-only compliance instead of practical risk reduction.

Who We Serve

The clients that need BTC most.

BTC is designed for businesses that need a security specialist when something happens, before cyber insurance renewal, or before moving into SOC-as-a-Service monitoring.

Law Firms

Privileged communications, trust accounts, real estate closings, and partner mailboxes make law firms prime targets for BEC and wire fraud.

Focus: ATO/BEC response
Risk: wire fraud + client confidentiality
Fit: IR, M365 assessment, hardening

CPA & Accounting Firms

Tax data, payroll records, bank information, and seasonal pressure create perfect conditions for phishing, account takeover, and data theft.

Focus: pre-season hardening
Risk: payroll + tax data exposure
Fit: readiness, ATO response, monitoring handoff

Real Estate & Title Offices

Closing communications, multiple external parties, and urgent wire deadlines give attackers a direct path to high-dollar fraud.

Focus: wire fraud prevention
Risk: lookalike domains + inbox rules
Fit: email security, BEC response, SOCaaS

Insurance Agencies

Agencies hold policyholder PII, claims information, carrier access, and sensitive client communications that require stronger controls.

Focus: control validation
Risk: PII + carrier portal exposure
Fit: insurance readiness, assessment, hardening

Professional Services

Consulting firms, small medical offices, finance teams, and service businesses often have valuable data but no dedicated security owner.

Focus: practical risk reduction
Risk: client data + cloud misconfigurations
Fit: assessment, cleanup, readiness

Post-Incident Businesses

You had a scare, a phishing event, a compromised mailbox, or a cyber insurance renewal wake-up call. BTC helps you figure out what happened and what to fix.

Focus: investigation + remediation roadmap
Risk: attacker persistence + repeat compromise
Fit: IR, cleanup, SOCaaS handoff

How We Help

The Pattern

Most incidents do not start with advanced malware.

They start with a phished password, a weak MFA setup, a risky enterprise app, a hidden inbox rule, or an old admin account nobody removed.

That is why BTC focuses on Microsoft 365, identity, email, and tenant security first. It is where SMB incidents actually happen.

Credential Theft

Stolen passwords, MFA fatigue, and reused credentials become the first door in.

Mailbox Abuse

Forwarding rules, inbox rules, and hidden folders let attackers watch and wait.

Rogue Apps

Over-permissioned OAuth and enterprise apps can create long-term access paths.

Weak Evidence

No logs, no timeline, no documented process, and no proof for insurance or leadership.

Not sure where you fit?

Start with a short consultation. We will tell you whether you need incident response, an M365 assessment, tenant cleanup, readiness work, or a handoff into ongoing SOC-as-a-Service monitoring.
