24/7 Security Monitoring Built for Growing Phoenix Businesses
Most Phoenix businesses have antivirus, a firewall, and maybe an EDR tool running in the background. What they don't have is anyone actually watching what those tools are reporting. That gap, the space between "we have security tools" and "someone is monitoring them," is where breaches happen. Corporate Data Solutions (CDSI) closes that gap with Managed SIEM services that centralize your security data, flag real threats, and get a qualified team looking at them around the clock.
Why Corporate Data Solutions?

- A security-first approach that finds what other providers overlook
As always - very quick and responsive solutions. Whenever there are computer issues, it's hardly an interruption in the day because they are on-top of it.
Why Phoenix Businesses Struggle Without Managed SIEM
Security tools generate a lot of noise. Without someone correlating and acting on that data, most of it goes unread.
- Endpoint, firewall, and Microsoft 365 logs sit in separate systems that never talk to each other
- Suspicious sign-ins or after-hours access go unnoticed until real damage is done
- Internal IT staff are busy with helpdesk tickets, not full-time threat monitoring
- Alerts pile up until someone stops paying attention to all of them, including the real ones
- There is no documented incident response plan for when something actually triggers
- Compliance and cyber insurance requirements increasingly expect active log monitoring, not just log collection
Managed SIEM Services from CDSI
Assessment
Every engagement starts with a look at what you actually have in place today: which systems generate logs, where your Microsoft 365 environment stands on conditional access and MFA, and what visibility gaps already exist. CDSI identifies misconfigurations and unmonitored accounts before building the monitoring plan around them.
Implementation
CDSI connects your endpoints, network devices, servers, and Microsoft 365 tenant into a centralized SIEM platform. Changes are rolled out in stages rather than all at once, so daily operations aren't disrupted while monitoring goes live.
Ongoing Support
Once live, your environment is backed by CDSI's help desk and rigid response standards: phone calls answered by the third ring, ticket responses within 15 minutes, and no cap on support hours. Security findings are handled with the same urgency as any other IT issue.
Security & Monitoring
CDSI's 24/7 monitoring correlates activity across your environment and escalates real threats instead of burying your team in noise. Suspicious logins, privilege escalations, and unusual data access are flagged and investigated, not just logged and forgotten.
Managed SIEM works best alongside a broader security posture.

The Numbers Behind the Risk
The financial and regulatory stakes of skipping active monitoring keep climbing. In 2025, the average global cost of a data breach dropped to $4.44 million, but organizations still took a mean of 241 days to identify and contain a breach, according to IBM's 2025 Cost of a Data Breach Report. That's the better outcome. Small and mid-sized businesses fare worse against one specific threat: 88% of SMB breaches in 2025 involved a ransomware component, compared to 39% at larger enterprises, according to Verizon's 2025 Data Breach Investigations Report.
Arizona businesses also carry a legal clock once a breach is confirmed. Under A.R.S. § 18-552, the Arizona Attorney General's Office requires affected individuals to be notified within 45 days of determining a breach occurred, with additional reporting to the state and national credit agencies if more than 1,000 residents are involved. Active monitoring is what gives you the time to investigate and respond within that window instead of scrambling on day 44.
Why Businesses Choose CDSI
CDSI's approach to security starts with what's actually happening inside your environment, not just what looks configured on the surface. Many engagements begin by uncovering misconfigured conditional access policies, unused admin accounts, or former employees who still have access. Managed SIEM is where that same philosophy becomes continuous.
Instead of a one-time audit, you get ongoing environment reviews, clear remediation when something is found, and a team that treats security monitoring as core service delivery rather than an upsell. CDSI's Microsoft-first expertise means your SIEM implementation is built around how your business actually uses Microsoft 365, not a generic template.

FAQ
What is Managed SIEM, and do I need it if I already have antivirus and a firewall? Managed SIEM (Security Information and Event Management) centralizes logs from your endpoints, network, and cloud services, then actively monitors them for signs of a threat. Antivirus and firewalls block known threats; SIEM catches the activity that gets past them, like a compromised login or unusual data access.
How is this different from CDSI's endpoint protection or EDR services? EDR protects and responds at the device level. Managed SIEM pulls data from EDR, your Microsoft 365 tenant, network devices, and more into one place so patterns across your whole environment, not just one device, can be spotted and acted on.
How much does Managed SIEM cost for a small or mid-sized business? Pricing depends on the number of devices, users, and data sources being monitored. CDSI starts with an assessment of your current environment to scope an accurate, transparent cost before any commitment.
