Most security work happens in our 24/7 NOC/SOC. When a firewall, switch or infected laptop needs hands on site, engineers take the 105 or the 91 west from our Santa Fe Springs office.
BTI Communications Group, LTD. provides managed cybersecurity to businesses in the South Bay 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 Torrance, El Segundo, Gardena, Hawthorne, Carson and Redondo Beach, 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 14 miles from Gardena, 17 miles from Torrance and 20 miles from El Segundo 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 South Bay holds a deep cluster of aerospace, space, defense and technology companies in El Segundo, Hawthorne and Torrance, machine shops and distribution sites in Gardena and Harbor Gateway, and port and marine businesses around San Pedro and Wilmington. Each one draws a different kind of attack.
Suppliers in El Segundo, Hawthorne and Torrance 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.
Machine shops and distribution sites in Gardena, Torrance and Harbor Gateway cannot ship when ERP, WMS or scanner networks are down. Detection plus tested, offline backups decide whether an attack is an incident or a shutdown.
Truck yards and marine businesses around the Port of Los Angeles see spoofed broker emails and payment change requests. 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 South Bay 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 South Bay 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 South Bay 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 South Bay.

BTI Communications Group, LTD. provides managed cybersecurity to businesses in the South Bay 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.
No. Our Southern California office is at 12155 Mora Dr, Units 1 and 2, Santa Fe Springs, CA 90670, about 14 miles from Gardena and 17 miles from Torrance in a straight line. Security monitoring runs from our 24/7 NOC/SOC, and the 105 and the 91 bring engineers west into the South Bay.
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 South Bay, discovery specifically addresses technical supplier requirements, segmentation and business-led containment.
South Bay security pricing depends on protected systems, identities, sites and the level of testing and governance selected. Supplier evidence work, log retention and recovery obligations are scoped explicitly. No local competitor's price is presented as BTI pricing.
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 South Bay site in that time. Field work is prioritized and arranged under the service agreement.
South Bay service is delivered from BTI's Santa Fe Springs office, not a Torrance or El Segundo branch. Field scheduling accounts for incident severity, building access and travel across the region; remote response is distinct from physical arrival.
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 technical supplier requirements, segmentation and business-led containment, 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.
Our South Bay service area includes Torrance, El Segundo, Gardena, Carson, Redondo Beach, Hawthorne, Lawndale and Hermosa Beach. Tell us each site address so we can define the delivery plan.
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.
Choose an actual customer requirement and trace the information, accounts and application it concerns. Identify the evidence already available and the missing owner. Do not select a framework or credential solely because neighboring suppliers mention it.
No. Authorized testing examines exploitation within an agreed boundary, while a contract can include broader governance and operational duties. Ask for scope, exclusions, prioritized findings and verification. The report should inform the requirement review, not replace it.
SOC is the security operating function, SIEM relates events and MDR investigates with agreed actions. Check signals and containment authority for the specific account and network boundary. Alert forwarding leaves work your internal team must be prepared to perform.
Not alone. Cameras, controllers, supplier sessions and application permissions can have different owners and coverage. Map the boundary and legitimate connections, then align device safeguards, MFA and network rules. Retain explicit decisions for unsupported systems.
Authorized staff should complete the selected task with clean access and restored dependencies. Confirm that reconnecting does not reopen the suspect permission or network path. State which external applications or building functions were not exercised.
Assign the business information owner, permission administrator and review duty under the actual subscription. The platform does not interpret your customer contract. Include the outside specialist's authorized purpose and removal decision in the responsibility map.
Define immediate operator authority and the business or property approver for consequential changes. Include the equipment specialist and alternate contact where needed. Rehearse the legitimate function so containment is not improvised against an unknown dependency.
Determine whether CCPA as amended by CPRA applies, with adviser review of conditions and exemptions. Map relevant personal information and applicable request, permission and retention ownership. Technical information and personal information should not be treated as automatically identical legal categories.
Combine selected identity, endpoint and network events with the current connection map. Agree collection, retention and access to vendor-controlled logs. A device event may not show which shared-building or remote-maintenance path was involved.
Yes. Prioritize consequential exposure and unclear authority, then schedule changes requiring equipment validation or customer coordination. Give each phase acceptance and remaining-risk ownership. An unfinished integration should not appear as operating coverage.
Identify selected controls, systems, reporting checks and the legitimate workflow to validate. Agree documentation and reversal for boundary changes. Any physical installation is planned from Santa Fe Springs with property access; no South Bay branch or universal arrival time is claimed.
Yes. Preserve their application and equipment knowledge while assigning selected security duties. Inventory credentials, diagrams and evidence, then accept monitoring and recovery handoffs before retiring old tools. Co-managed scope should state who approves and validates network changes.
