Most security work happens in our 24/7 NOC/SOC. When a firewall, switch or infected laptop needs hands on site, engineers take the 605 north from our Santa Fe Springs office straight into the valley.
BTI Communications Group, LTD. provides managed cybersecurity to businesses in the San Gabriel Valley from its Southern California office in Santa Fe Springs, and has been in business for over 40 years. Our 24/7 NOC/SOC runs detection and response, email security, identity protection, patching and backups for companies in Pasadena, City of Industry, El Monte, Alhambra, Arcadia and West Covina, and penetration testing is run with our independent testing partner.

| Question | Direct answer |
|---|---|
| Who provides it? | BTI Communications Group, LTD., through a 24/7 NOC/SOC, with engineers based at our Southern California office in Santa Fe Springs. |
| How far is the office? | About 7 miles from Hacienda Heights, 9 miles from City of Industry and El Monte and 15 miles from Pasadena in a straight line. Remote support starts right away. |
| What does a program include? | Managed detection and response, email security, MFA, patching, backups, testing and a written incident plan. |
| Can you help with insurance or customer questionnaires? | Yes. We put the technical controls in place and document them for your carrier or customer. |
| Can you work with our IT team? | Yes. Security can be fully managed or co-managed alongside your internal IT lead or current provider. |
| How do we start? | A free consultation and a credential-free Level 1 pen test of 3 to 5 machines you choose. |
A BTI engineer reviews your risks, compliance needs and insurance requirements with you. Then we run a credential-free Level 1 penetration test of 3 to 5 machines you choose, with our independent testing partner.
The San Gabriel Valley mixes warehouses, importers and distribution centers along the 60 freeway, plants and food production in El Monte, Irwindale and Pomona, professional and financial offices in Pasadena and Arcadia, and water utilities and public agencies across the valley. Each one draws a different kind of attack.
Utilities and special districts need segmented networks and monitored systems. San Gabriel Valley Water Company, which serves approximately 94,000 customers, uses BTI as its single source provider of VoIP, network and physical security systems, plus cybersecurity monitoring and protection.
Warehouses and importers in City of Industry and Walnut cannot ship when WMS, scanner or customs systems are down. Detection plus tested, offline backups decide whether an attack is an incident or a shutdown.
Fake invoices and wire change requests hit engineering, legal, accounting and wealth management offices. Email filtering, MFA and staff training stop most of them.
Carriers ask about MFA, endpoint detection and response, backups and training before they renew. Gaps mean higher premiums or exclusions.
A new building or an acquired office often lands on a different network, with different admin accounts and no shared baseline. We bring every site onto one standard with documented exceptions.
Cameras, door controllers and timeclocks are often the least protected computers a company owns. See IoT security and AI data loss prevention.

Most San Gabriel Valley clients come to us with a deadline: an insurance renewal, a customer questionnaire or an audit. We map the controls you have against what is being asked and close the gaps in order.

Each unchecked item is a common way attacks succeed.
Not sure how many you can check? The free consultation and pen test answers that for you, or start with a cybersecurity assessment.
Testing frequency varies by client requirement and compliance scope. By default, BTI recommends monthly vulnerability scans and quarterly penetration tests. Financing at 3.99% is available for qualified buyers, subject to credit approval, for security hardware and projects.
Call your insurer first if you have cyber coverage, since many policies name the response firms you must use. We work alongside them.
Both plans give you ongoing testing by our independent testing partner and reports that show risk going down over time.
Cyber Liability Essentials covers the baseline many insurers ask about. Cyber Watch is our pen testing plan for organizations that want testing on a regular schedule. Your engineer recommends one after the free pen test.

Some companies in the San Gabriel Valley have no internal IT staff; others have one IT lead covering several buildings. Either way, each tool gets a named owner.
| Fully managed | Co-managed | |
|---|---|---|
| Good fit for | No internal IT staff | An IT lead or small team |
| Alert handling | BTI 24/7 NOC/SOC | BTI 24/7 NOC/SOC, with your team on agreed escalations |
| Patching and MFA | BTI | Split by system, in writing |
See co-managed IT.
Security tools fail when no one owns them. Because BTI also runs IT support, the same team that patches your servers responds to alerts and fixes what a test finds. Clients who want both use managed IT in the San Gabriel Valley or managed IT across Los Angeles.
Opening a new building, moving offices or replacing a firewall? Our Los Angeles IT project team builds security into the network from day one. Teams adopting AI tools can add managed AI automation in Los Angeles with AI governance and a Shadow AI and PII data assessment.
We also secure the cameras and door controllers we install, so building systems are not the weak link. See security cameras and access control in the San Gabriel Valley.

BTI Communications Group, LTD. provides managed cybersecurity to businesses in the San Gabriel Valley from its Southern California office in Santa Fe Springs, including MDR, email security, identity protection, patching, backups and penetration testing with an independent testing partner, run through our 24/7 NOC/SOC. Call 323-510-8003.
A working session with a BTI engineer on your risks and requirements, plus a credential-free Level 1 penetration test of 3 to 5 machines you choose, run with our independent testing partner. You keep the report and the ranked roadmap. There is no cost and no obligation.
Yes. Our Southern California office is at 12155 Mora Dr, Units 1 and 2, Santa Fe Springs, CA 90670, just south of the valley, about 9 miles from City of Industry and 15 miles from Pasadena in a straight line. Security monitoring runs from our 24/7 NOC/SOC.
Disconnect affected devices from the network without turning them off, call your cyber insurer if you have coverage, and call your security provider. Do not pay a ransom or wipe systems before evidence is preserved.
Yes. CMMC and other compliance work is completed and contracted by BTI and its partners, including top industry professionals in each category.
Testing frequency varies by client requirement and compliance scope. By default, BTI recommends monthly vulnerability scans and quarterly penetration tests as part of ongoing security monitoring.
BTI can operate identity and endpoint protection, threat investigation, email defenses, patching, testing and governance for your organization. The itemized proposal identifies the services selected, the assets covered and the responsibilities your staff keep. For San Gabriel Valley, discovery specifically addresses cloud sharing, diverse facilities and evidence maintained throughout the year.
The scope of identity management, monitoring, backup review, testing and governance determines the proposal. A single-office professional firm and a distributed manufacturer should not receive an unexplained identical security bundle.
Managed clients receive technical support in real time by phone and within 15 minutes by email. Those are support-response standards, not a promise that an engineer will arrive at a San Gabriel Valley site in that time. Field work is prioritized and arranged under the service agreement.
BTI's team travels to San Gabriel Valley sites from Santa Fe Springs; we do not claim a Pasadena or West Covina office. Remote work and planned field visits are coordinated around site requirements, incident priority and actual travel conditions.
Yes. Co-managed security assigns agreed controls and investigations to BTI while your internal team or current provider retains its defined duties. For this region, the handoff plan should explicitly cover cloud sharing, diverse facilities and evidence maintained throughout the year, including who authorizes an operational change.
We compare requested controls with deployed settings and supporting records, then organize the gaps into a practical plan. Industry-specific requirements are scoped to your business; no provider can guarantee an insurance decision, legal compliance or a successful certification outcome.
The regional team supports Pasadena, Arcadia, Monrovia, El Monte, West Covina, Alhambra, San Gabriel and Baldwin Park, plus other scoped San Gabriel Valley locations.
Incident response is included in BTI managed security as defined in the service agreement. Your written plan identifies authorized containment, evidence handling and recovery responsibilities. If cyber insurance applies, involve the insurer promptly because its policy may specify the response firms it requires.
Start with a shared client folder and its administrator. Identify approved users, the sponsor and the last permission review. Use the assessment to clarify missing evidence and the controls your current provider actually operates.
No. A scan searches known technical weaknesses; a permission review checks who should have access. Authorized penetration testing explores exploitation within a separate scope. Select the work your client-sharing workflow needs and document exclusions and remediation.
Ask which identity and application signals are investigated and who may act. SOC is the security operating function, SIEM relates logs and MDR includes agreed response. A forwarded alert can leave the practical investigation duty with your staff.
Yes, if cloud invitations, delegated access or administrator roles are inappropriate. Device controls and MFA need a business-owned permission review. Record why an external specialist has access and what ends that permission when the engagement changes.
Have authorized users complete a representative client task using restored information and clean access. Check sharing and application dependencies, not just file availability. Record what was not exercised and the owner of any failed step.
The service operates its infrastructure, while your organization assigns the account, sharing, administrator and recovery duties it retains. Check the actual subscription and the current provider's scope. A platform invoice does not identify the business sponsor for a permission.
The incident plan should identify the reviewing operator, immediate authority, business approver and alternate. Use trusted contact details. If an application vendor controls evidence or restoration, define that handoff before the affected mailbox becomes the only communication route.
For a covered business, CCPA as amended by CPRA can inform personal-information handling, applicable rights requests and retention ownership. Have advisers determine coverage and exemptions. A nonprofit or education organization should not inherit a professional firm's legal conclusion by proximity.
Keep dated access reviews, device reporting, patch exceptions and restore results with their source and owner. Use relevant cloud logs where selected. A statement that a tool was purchased is not evidence that every application or user was covered.
Yes. Prioritize consequential permissions and missing ownership, then schedule technical changes and recovery checks. Give each phase acceptance and an owner for unfinished risk. The evidence file should show progress and limits rather than imply future work already operates.
Agree the selected controls, permissions, reporting checks and handover. Validate the legitimate client workflow after configuration. Physical installation is separately planned from Santa Fe Springs for site access and travel; no separate Valley branch or arrival guarantee is implied.
Yes. Inventory existing ownership, evidence and open exceptions, then assign investigation, testing and governance explicitly. Accept monitoring and recovery handoffs before removing previous tools. Co-managed work should preserve application knowledge and the history behind unfinished actions.
