Most security work happens in our 24/7 NOC/SOC. When a firewall, switch or infected laptop needs hands on site, engineers leave from our Santa Fe Springs office, a few miles from Norwalk, Downey and Whittier.
BTI Communications Group, LTD. provides managed cybersecurity to businesses in Long Beach and the Gateway Cities 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 Long Beach, Cerritos, Downey, Norwalk, Carson and Lakewood, 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? | Our office is in Santa Fe Springs, one of the Gateway Cities: about 3 miles from Norwalk and Downey, 6 miles from Cerritos and 14 miles from downtown Long Beach in a straight line. |
| 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 Gateway Cities mix the logistics buildings, truck yards and cold storage that serve the Port of Long Beach, machine shops and aerospace suppliers in Long Beach, Paramount and South Gate, and offices and medical groups in Downey, Cerritos and Lakewood. Each one draws a different kind of attack.
Warehouses and truck yards along the 710 and the Alameda Corridor cannot move freight when WMS, scanner or gate systems are down. Detection plus tested, offline backups decide whether an attack is an incident or a shutdown.
Machine shops and aerospace suppliers are asked to prove controls before they win or keep contracts. CMMC and other compliance work is completed and contracted by BTI and its partners, including top industry professionals in each category.
Spoofed broker emails, fake invoices and payment change requests hit logistics and finance teams across Carson, Compton and Rancho Dominguez. Email filtering, MFA and verified call back rules 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 Long Beach and Gateway Cities 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 Long Beach and the Gateway Cities 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 Long Beach and the Gateway Cities 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 Long Beach and the Gateway Cities.

BTI Communications Group, LTD. provides managed cybersecurity to businesses in Long Beach and the Gateway Cities 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, inside the Gateway Cities, about 3 miles from Norwalk and Downey and 14 miles from downtown Long Beach. 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 Long Beach and Gateway Cities, discovery specifically addresses shipping/finance permissions, connected buildings and a real Gateway Cities office.
A multi-site Gateway Cities quote starts with the assets and business functions being protected, not just the number of employees. We separate detection, identity controls, testing, governance, backups and field-service responsibilities so a security program can work alongside your current IT team.
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 Long Beach and Gateway Cities site in that time. Field work is prioritized and arranged under the service agreement.
Service planning covers Long Beach, Signal Hill, Lakewood, Cerritos, Downey, Norwalk and Paramount from the actual Santa Fe Springs office. There is no separate BTI Long Beach branch. On-site arrangements reflect the address, incident priority, access restrictions and 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 shipping/finance permissions, connected buildings and a real Gateway Cities office, 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.
Long Beach and Gateway Cities coverage includes Long Beach, Signal Hill, Lakewood, Cerritos, Downey, Norwalk, Paramount and Santa Fe Springs, with other regional addresses reviewed during discovery.
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.
Trace one shipment and sensitive finance change through its accounts, approvers and outside portals. Identify what the current provider operates and what remains a business decision. Use the assessment to test the relevant boundaries, not merely count protected laptops.
The published program describes recurring independent testing. Confirm authorized assets, cadence and retesting, then assign remediation. A technical finding needs a business owner when changing it could affect dispatch or a partner connection.
An alert service notifies someone; MDR investigates and performs agreed response actions. SOC is the operating function and SIEM relates logs. Confirm who can revoke a suspect identity and who handles payment or shipping consequences.
No. A permitted account or convincing message can still lead to a harmful approval. Combine device and email controls with role separation, MFA and an independently verified change process. Finance decisions should not rely on the same mailbox for both request and verification.
Prove the selected shipping or finance task works with clean access and restored dependencies. Identify the partner platform involved and what was excluded. A successful backup job alone does not show dispatch has recovered or a compromised approval route is safe.
Assign your organization's user, supplier and administrator decisions under the actual subscription. The platform does not decide which dispatch user should change financial details. Document that approval and the removal process when a role ends.
The plan should name immediate operator authority, the business approver and alternate contacts for finance and operations. Rehearse the effect of disabling the account. Preserve a clean communication route when the original email conversation cannot be trusted.
Confirm whether CCPA as amended by CPRA applies and which exemptions matter, with adviser input. Map relevant personal information, permissions, retention and request ownership. Location or a security subscription alone does not establish coverage or a compliance guarantee.
Review sign-ins, mailbox changes and relevant platform events alongside device and network signals. Agree collection and retention. A partner-hosted portal may require a separate evidence route; do not assume endpoint monitoring supplies its entire history.
Yes. Address consequential access and approval gaps first, then schedule application or site changes with the operating team. Each phase needs acceptance and a remaining-risk owner. Keep dispatch and finance responsibility continuous while later upgrades are pending.
BTI's Southern California office is in Santa Fe Springs. Implementation covers the selected controls and validation; any physical work has an agreed site and access plan. There is no separate Long Beach branch or uniform arrival promise.
Yes. Document retained platform duties, administrator ownership, monitoring and recovery handoffs. Accept the new arrangement before retiring old access. Co-managed security can preserve useful application support while clarifying finance, dispatch and incident responsibilities.
