What to Do When Your Business Is Under Attack
If you're dealing with a live security incident, ransomware, a compromised account, or unexplained activity in your Microsoft 365 tenant, waiting on hold isn't an option. Corporate Data Solutions (CDSI) provides security incident response in Phoenix for businesses that need containment fast and a clear plan for what happens next. Most local businesses discover a gap in their response plan the moment they need it most. CDSI closes that gap before, during, and after an incident.

- Unlimited support hours with no hidden costs or billing surprises
Why Businesses Struggle with Incident Response
Most SMBs in the Phoenix area find out their incident response plan doesn't exist, or doesn't work, only after something has already gone wrong. Common gaps CDSI sees when stepping into a new environment include:
- No documented response plan, so the first hour of an incident is spent figuring out who does what
- MFA and conditional access policies that are partially enabled or inconsistently enforced
- Former employees or vendors who still have active accounts and access
- No centralized monitoring, so suspicious activity goes unnoticed for days or weeks
- Backups that have never been tested, discovered only when a restore is actually needed
- A previous IT provider with slow response times and no clear escalation process

Assessment
CDSI starts by identifying what's actually happening in your environment, not just what your current setup appears to show. This includes reviewing Microsoft 365 configurations, admin privileges, conditional access policies, and endpoint status to determine the scope of an active incident or the gaps that would slow down a response.
Containment and Response
When an incident is active, CDSI moves to lock down the entry point immediately. That means securing compromised accounts, revoking unauthorized access, isolating affected devices, and shutting off remote access tools being used against you. The goal is to stop the bleeding before assessing full impact.
Ongoing Support
Incident response doesn't end when the immediate threat is contained. CDSI works with leadership through recovery, communicates clearly about what happened and what changed, and builds the documentation your business needs going forward, including runbooks and updated access records.
Security and Monitoring
Post-incident, CDSI implements 24/7 endpoint detection and response monitoring, enforces MFA and conditional access across your tenant, and reviews admin access on an ongoing basis so accounts and permissions don't quietly drift out of compliance again.

The Cost of Getting This Wrong
Breach costs for U.S. organizations hit an all-time high in 2025, reaching $10.22 million on average as IBM's 20th annual Cost of a Data Breach Report found, with regulatory fines and detection costs pushing the U.S. figure well above the global average. Response speed matters just as much as prevention. According to the 2026 Verizon Data Breach Investigations Report, ransomware was involved in 48% of breaches last year, and the median time to full incident resolution climbed to 43 days, up from 32 days the year before.
For a business without a structured response plan, that gap between detection and containment is where the real damage happens.
Why Businesses Choose CDSI
Businesses that switch to CDSI are usually leaving a provider that took days to respond, made them re-explain their setup on every call, or never caught the misconfigurations sitting in their environment. CDSI operates differently. Every engagement starts with what's actually happening in your systems, not a surface-level review.
Onboarding is deliberately incremental. CDSI locks down passwords and remote access points immediately, then works through a structured 30-day stabilization process to bring your network, cloud environment, and users up to security best practices without disrupting how your team works day to day.
Corporate Data Solutions has been a partner for us for many years. They professional and efficient. They identify problems before we are even aware. All of the support people are courteous and helpful.
