PLANO
One Security Posture for Many Campuses, Tenants and Acquired Teams
Plano is home to national headquarters, and one security decision made here has to work for every branch, plant, store, and remote employee.
Acquisitions make that harder: multiple directories, email domains, cloud subscriptions, and orphaned admin accounts. Our cybersecurity consulting in Plano starts with that identity layer, folding acquired tenants into one governed model, then extends to detection, cloud posture, devices and data.
The DESSS security consulting and advisory practice works alongside our Microsoft, cloud, and application teams. We assess, design, implement, and co-manage monitoring.
Where engagements often start
Directory and tenant consolidation after a merger, Conditional Access redesign, SOC 2 or ISO 27001 readiness, and endpoint coverage gaps across sites.
Technology we secure
Active Directory and Entra ID, Microsoft 365, Azure and AWS, Windows and macOS fleets, SaaS applications and identity providers such as Okta.
Frameworks and laws we map
NIST CSF, ISO 27001, SOC 2, PCI DSS, HIPAA, SOX and the Texas Data Privacy and Security Act, based on your obligations.

LOCAL RISK PICTURE
Why Plano Companies Need Cybersecurity Consulting
Plano businesses tend to be large, distributed and acquisitive. Those traits create specific security problems that a single firewall or antivirus product cannot solve.
Mergers leave identity gaps
Each acquisition brings its own directory, admin groups and trust relationships. Until they are consolidated, attackers can use the weakest inherited environment as a path into the parent company.
Headquarters serve many sites
Policies set on a corporate campus must reach regional offices, stores, plants and remote staff. Gaps in device enrollment or network access at one site expose the entire organization.
SaaS and cloud sprawl quickly
Business units adopt SaaS tools and cloud subscriptions faster than security teams can review them, leaving shadow admin accounts, unmanaged data and public storage behind.
Customers demand attestations
Technology and service providers are asked for SOC 2 reports, ISO 27001 alignment and long security questionnaires before contracts are signed or renewed.
Hybrid work blurs the perimeter
Campus employees split time between office and home, and contractors join through their own devices. Access decisions have to rely on identity and device health, not network location.
Privacy rules reach every business unit
Customer, member and patient data spread across many systems falls under HIPAA, GLBA, PCI DSS or the Texas Data Privacy and Security Act. Knowing where that data lives is the first requirement.

MICROSOFT SECURITY
Microsoft Security Consolidation for Plano Headquarters
What is included in the Microsoft security stack? The Microsoft security stack is the group of identity, endpoint, detection and information protection products that ship with many Microsoft 365 and Azure agreements: Active Directory, Microsoft Entra, Microsoft Defender with Sentinel, Microsoft Intune and Microsoft Purview. Configured together, they cover identity, devices, threats and data.
For multi-site enterprises, the hardest Microsoft problem is usually not a missing feature but fragmentation. We see headquarters tenants running next to tenants from acquired companies, with separate Conditional Access rules, duplicate guest accounts and inconsistent device policies. An AD to Entra migration plan, combined with a cross-tenant cleanup, lets the business standardize sign-in, retire legacy trusts and apply one set of protections everywhere.
Once identity is consolidated, Defender, Intune and Purview can be rolled out in waves by business unit. Each wave has clear acceptance criteria, so headquarters security teams can show progress to leadership and acquired teams are not surprised by changes to how they work.
Microsoft Active Directory
Security assessment, tier zero cleanup and decommissioning of trusts left behind by acquired companies.
AD DS design, hardening, migration, and forest recovery for the on-premises identity core.
Microsoft Entra
Cross-tenant consolidation, Conditional Access standards and governed guest access for partners and subsidiaries.
Entra ID, Conditional Access, PIM, and identity governance for cloud identity and Zero Trust.
Microsoft Defender
One Defender XDR and Sentinel view across every business unit, with alert routing that respects regional IT ownership.
Defender XDR and Microsoft Sentinel SIEM deployed, tuned, and run as a working detection capability.
Microsoft Intune
Autopilot enrollment and compliance policies that bring acquired device fleets under the corporate baseline.
Intune security baselines, Autopilot provisioning, and co-management for compliant devices.
Microsoft Purview
Sensitivity labels applied consistently to board materials, deal documents, customer records and source code.
Information protection, DLP, records management, and eDiscovery across Microsoft 365.
IDENTITY, DETECTION AND TESTING
Identity, Detection and Testing Consulting in Plano
These five domains control who gets in, what they can reach, and how quickly suspicious activity across your sites is caught and contained.
IAM & PAM
What is identity and access management? Identity and access management (IAM) decides who can access which applications and data, using single sign-on, multifactor authentication and role-based access. Privileged access management (PAM) adds approval, time limits and recording for administrator and service accounts.
After an acquisition, a Plano headquarters may need to merge large numbers of identities from several directories while the business keeps running. We design role-based access control around the combined org chart, deliver a single sign-on and MFA rollout that covers inherited apps, and automate joiner-mover-leaver steps from the HR system.
–Identity consolidation across acquired directories
–Unified SSO, MFA and role design
–Privileged account discovery and vaulting
SOC & MDR
What is a SOC and what is MDR? A security operations center (SOC) monitors systems and investigates threats using a SIEM and defined response procedures. Managed detection and response (MDR) delivers that monitoring, hunting and response as a service, alongside or instead of an internal team.
Distributed enterprises need a SOC that sees every site, tenant and cloud account in one place. We perform a SOC readiness assessment, consolidate log sources from acquired businesses into a single SIEM, write detections for identity abuse and SaaS misuse, and run or co-manage monitoring with headquarters staff.
–Log consolidation across business units
–Detections for identity and SaaS abuse
–Run or co-managed monitoring and escalation
VAPT, penetration testing & red team
What is VAPT? Vulnerability assessment and penetration testing (VAPT) pairs broad scanning with hands-on testing that exploits weaknesses as a real attacker would. Red and purple team exercises extend this into realistic campaigns that measure detection and response.
For technology firms, testing scopes often center on SaaS platforms, customer APIs and cloud tenants. For acquisitive enterprises we add an Active Directory and Entra review of newly connected subsidiaries, and run phishing and social engineering simulation to measure how staff across sites respond.
–Application, API and cloud penetration testing
–Pre- and post-acquisition environment testing
–Phishing simulation and red team exercises
Cloud security consulting
What is cloud security consulting? Cloud security consulting helps organizations configure and operate Azure, AWS and SaaS platforms safely. It covers account and subscription structure, identity permissions, network exposure, workload and container protection, and monitoring for configuration drift.
Many companies here run cloud estates assembled from several acquisitions, each with its own subscriptions and conventions. We run a cloud migration security review before workloads move, build an Azure landing zone with enforced guardrails, and bring orphaned AWS accounts under central posture monitoring.
–Subscription and account consolidation
–Azure and AWS guardrails and policy
–SaaS security posture review
Zero Trust and network security
How does Zero Trust security work? Zero Trust security works by verifying every access request on identity, device health and context, never on network location alone. Users receive only the access they need, sensitive systems are segmented, and sessions are continuously evaluated.
Multi-site enterprises often still route branch and remote traffic through a headquarters VPN. We design Zero Trust network access and SASE to replace that model, give acquired units application-level access before networks are merged, and segment campus networks so a compromised device stays contained.
–ZTNA and SASE architecture
–Access for acquired units before network integration
–Campus and branch segmentation
PROTECTION, GOVERNANCE AND OPERATIONS
Device, Data, Compliance and Software Security for Plano Organizations
These domains protect endpoints and information wherever employees work, document compliance for customers and auditors, and secure the software and connected systems your business builds and runs.
Endpoint and email security
What does endpoint security involve? Endpoint security involves protecting computers, servers and mobile devices with EDR or XDR, secure configuration baselines and disciplined patching. Email security complements it by stopping phishing, malware and impersonation before users see them.
Acquired companies often arrive with a different antivirus product, or none at all. We plan EDR and XDR deployment across every fleet, align Windows and macOS hardening, and handle mobile device and BYOD security for sales and field teams who never visit a Plano campus.
–Single EDR platform across all business units
–Windows and macOS hardening baselines
–Mobile and BYOD protection
Data protection and cyber resilience
What does data protection involve? Data protection involves knowing where sensitive information lives, controlling who can use it and making sure it can be recovered. It combines classification, encryption, loss prevention, immutable backup and tested disaster recovery.
Merger and divestiture work moves large volumes of customer and employee data between systems. We use Purview sensitivity labels and data loss prevention policies to keep deal documents and personal data under control, then run a ransomware readiness assessment to confirm backups and recovery plans cover every newly joined unit.
–Data discovery and classification
–DLP across email, endpoints and cloud
–Ransomware readiness and recovery testing
GRC and compliance
What is governance, risk and compliance? Governance, risk and compliance (GRC) sets security policy, measures risk and demonstrates to customers, auditors and regulators that controls operate as intended. It includes risk assessments, policy frameworks, audit preparation and fractional CISO leadership.
Technology and service providers frequently need SOC 2 reports and ISO 27001 alignment, while public headquarters answer to SOX auditors and boards. We harmonize policies across acquired entities, prepare cyber insurance readiness evidence, and provide fractional CISO services for leadership teams that need security direction without a full-time hire.
–SOC 2 and ISO 27001 readiness
–Policy harmonization after acquisitions
–Fractional CISO and board reporting
Application security and DevSecOps
What is DevSecOps? DevSecOps is the practice of building security into software delivery, so threat modeling, code analysis, dependency checks, secrets management and security testing run as part of normal development rather than as a final gate.
Software companies and enterprise development teams in Plano ship SaaS products, internal platforms and customer apps on tight cycles. We set up a secure SDLC program, add scanning to CI/CD pipelines, and perform code security review on high-risk components such as authentication, billing and multi-tenant data access.
–Secure SDLC program design
–Pipeline scanning and secrets management
–Manual review of high-risk code
OT, ICS and IoT security
What is IoT and OT security? OT security protects industrial controls and the physical processes they run, while IoT security covers connected devices such as cameras, badge readers, sensors and smart building systems. Both prioritize availability and safe operation.
Corporate campuses depend on building automation, badge systems, cameras and conference room devices, and many headquarters also oversee plants or distribution centers elsewhere. We inventory these devices, separate them from user networks, and apply IoT device security standards that headquarters can enforce at every site.
–Campus IoT and building system inventory
–Device network segmentation
–Security standards for remote plants and facilities

ASSESSMENT PROCESS
Our Cybersecurity Assessment Process for Plano Organizations
A cybersecurity assessment is an organized review of your identities, systems and controls that ends with a ranked set of risks and a practical plan to reduce them. For Plano clients it runs in five phases.
STEP 01
Frame the enterprise
We agree on the business units, campuses, tenants and recently acquired companies in scope, and on what leadership most needs to learn.
STEP 02
Inventory identities and assets
Discovery covers directories, cloud subscriptions, SaaS apps, devices and network zones, including the shadow systems acquisitions bring with them.
STEP 03
Test and compare controls
Configuration reviews, scans and agreed penetration tests are run against each environment, so weaker units stand out against the corporate baseline.
STEP 04
Map and prioritize risk
Findings are mapped to NIST CSF and to SOC 2, HIPAA, PCI DSS or SOX where they apply, then ranked by likelihood and business impact.
STEP 05
Sequence the integration roadmap
Remediation is ordered alongside planned migrations and integrations, with owners, effort and quick wins, and DESSS can help carry it out.
