Cloud security services across AWS, Azure, and GCP.
Lightbridge Cloud provides cloud security services across AWS, Azure, and GCP that protect data, identity, and infrastructure through the shared-responsibility model. We deliver identity and access management, data encryption, cloud security posture management, network security, and threat detection as assessment, hardening, and continuous monitoring.
What cloud security services are.
Cloud security services protect the data, applications, and infrastructure an organization runs on public cloud platforms. They span identity and access management, encryption and key management, configuration and posture management, network controls, and threat detection. The objective is to keep workloads confidential, available, and correctly configured as the environment changes.
Cloud security is not a single product. It is a set of controls applied continuously across providers. Lightbridge Cloud delivers it as a vendor-neutral practice across AWS, Azure, and GCP, mapping each control to the provider native tooling rather than bolting on a single tool and calling it secure.
The shared-responsibility model: provider versus customer.
Cloud security operates under the shared-responsibility model. The provider secures the cloud itself: the physical data centers, hardware, and virtualization layer. The customer secures what they run in the cloud: identity and access, data, configuration, network rules, and application code. This division is the single most misunderstood point in cloud security.
The split shifts with the service model. With infrastructure as a service, the customer owns the operating system, network configuration, and everything above it. With software as a service, more responsibility moves to the provider, though identity and data governance stay with the customer. Lightbridge Cloud defines the responsibility boundary for each workload at the start of an engagement so nothing falls into a gap that neither side is watching.
Core domains of cloud security at Lightbridge Cloud.
Identity and Access Management
Least-privilege IAM design across AWS, Azure, and GCP. Role and policy review, federation and SSO, multi-factor enforcement, and removal of standing privileged access in favor of just-in-time elevation.
Data Encryption and Key Management
Encryption at rest and in transit, centralized key management with KMS, Key Vault, or Cloud KMS, key rotation policies, and customer-managed key options for workloads with stricter custody requirements.
Cloud Security Posture Management
CSPM continuously scans cloud configuration against benchmarks such as CIS, detects misconfiguration and policy drift, and prioritizes findings by exploitability. Misconfiguration, not provider failure, drives most cloud breaches.
Network Security
Segmentation through VPCs and subnets, security group and firewall rule audits, private connectivity for sensitive workloads, egress control, and elimination of unintended public exposure of storage and compute.
Threat Detection and Response
Cloud-native detection with GuardDuty, Microsoft Defender for Cloud, or Security Command Center, centralized log aggregation, anomaly alerting, and documented response runbooks tied to defined severity tiers.
Vulnerability and Patch Management
Workload and image scanning, dependency vulnerability tracking, prioritized remediation by exposure, and patch deployment with change management and rollback procedures. Findings are tracked to closure, not just reported.
Cloud security versus on-premise security.
On-premise security defends a fixed perimeter around hardware the organization owns. Defenses concentrate at the network edge, and change is slow and controlled. Cloud security inverts this. There is no fixed edge to fortify. Identity becomes the perimeter, and the environment changes continuously as automation provisions and destroys resources.
That difference reshapes the discipline. Periodic audits cannot keep pace with infrastructure that mutates by the minute, so cloud security depends on continuous posture monitoring. Most cloud incidents trace to customer-side misconfiguration, not provider failure, which is why Lightbridge Cloud weights its delivery toward configuration management, identity hygiene, and automated detection rather than perimeter hardware. Cloud security work often pairs with a cloud migration or broader cloud consulting engagement.
How Lightbridge Cloud delivers cloud security.
Lightbridge Cloud delivers cloud security in three phases. Assessment measures the current posture against benchmarks such as CIS and NIST, surfaces misconfiguration and identity risk, and ranks findings by exploitability. Hardening remediates: it tightens IAM to least privilege, enforces encryption and key management, segments networks, and closes unintended exposure. Continuous monitoring then sustains the posture through CSPM, threat detection, and tracked remediation.
For defense and federal workloads, these controls map to formal compliance programs rather than generic hardening. Lightbridge Cloud aligns engagements to CMMC compliance and FedRAMP readiness, and applies the control set documented in the DFARS and NIST 800-171 guide. Security under continuous management pairs naturally with managed cloud services.

Cloud security services FAQ from Lightbridge Cloud.
What are cloud security services?
Cloud security services protect data, applications, and infrastructure running on cloud platforms such as AWS, Azure, and GCP. They cover identity and access management, data encryption and key management, cloud security posture management, network security, and threat detection. Lightbridge Cloud delivers these as assessment, hardening, and continuous monitoring across multi-cloud environments.
What is the shared responsibility model in cloud security?
The shared responsibility model divides security duties between the cloud provider and the customer. The provider secures the underlying infrastructure: physical data centers, hardware, and the virtualization layer. The customer secures what they put in the cloud: identity and access, data, configuration, network rules, and application code. The exact split shifts with the service model, with more falling to the customer for IaaS than for SaaS.
What is cloud security posture management (CSPM)?
CSPM is the continuous assessment of cloud configuration against security benchmarks and policy. It detects misconfiguration such as public storage buckets, overly broad IAM permissions, unencrypted volumes, and open network rules, then prioritizes findings by risk. Misconfiguration, not provider infrastructure failure, is the leading cause of cloud data exposure, which is why Lightbridge Cloud treats CSPM as a core control rather than an add-on.
How is cloud security different from on-premise security?
On-premise security defends a fixed perimeter with hardware you own and control. Cloud security operates in a shared-responsibility model where the provider secures the infrastructure and you secure identity, data, and configuration. The cloud perimeter is identity, not a firewall at the edge. Environments change constantly through automation, so cloud security depends on continuous configuration monitoring rather than periodic audits.
Which cloud platforms does Lightbridge Cloud secure?
Lightbridge Cloud is vendor-neutral and secures workloads across Amazon Web Services, Microsoft Azure, and Google Cloud Platform, including multi-cloud and hybrid environments. Controls are mapped to each provider native tooling: IAM, KMS, GuardDuty, and Security Hub on AWS; Entra ID, Key Vault, and Defender for Cloud on Azure; and IAM, Cloud KMS, and Security Command Center on GCP.
Does Lightbridge Cloud hold a security certification?
Lightbridge Cloud is pursuing ISO 27001 and SOC 2, with those certifications in progress rather than awarded. We operate to the corresponding controls today and do not represent ourselves as currently certified. For client engagements, our work is structured around recognized frameworks and benchmarks such as CIS and NIST and the controls of the relevant audit.
How does Lightbridge Cloud handle defense and federal compliance requirements?
For defense and federal workloads, Lightbridge Cloud maps cloud security controls to CMMC, FedRAMP, and NIST 800-171 rather than treating them as generic hardening. These programs have dedicated pages covering CMMC compliance, FedRAMP readiness, and the DFARS and NIST 800-171 control set. Cloud security establishes the technical foundation those compliance programs assess.
How does Lightbridge Cloud deliver a cloud security engagement?
Lightbridge Cloud delivers in three phases. Assessment establishes the current posture against benchmarks and identifies misconfiguration and identity risk. Hardening remediates findings: tightening IAM, enforcing encryption, segmenting networks, and closing exposure. Continuous monitoring then sustains the posture with CSPM, threat detection, and tracked remediation so configuration drift is caught as it happens.
