The headlines tell a familiar story. Breaches moving faster, attackers getting bolder, and boards demanding clearer answers. Against this backdrop, cybersecurity expert Opeoluwa Kajero is urging organizations to sharpen their focus on leading indicators of compromise—the red flags that, if seen in time, can prevent a headline.
“Start with identity because it is the new blast radius,” Kajero said. “Watch for impossible travel, MFA fatigue prompts, privilege creep, and dormant admin accounts that suddenly spring to life. When identity hygiene slips, excessive entitlements, stale service accounts, tokens without rotation, you’re essentially leaving the side door open, and attackers know it.”
He then points to cloud and SaaS posture drift as chronic blind spots. Misconfigured storage buckets, open management interfaces, overly permissive IAM roles, and untagged internet-facing services create opportunistic entry points. He recommends real-time policy-as-code guardrails, automated remediation for high-severity misconfigurations, and rigorous key management. When paired with continuous asset discovery, these controls keep sprawl from becoming exposure.
Kajero also stated that endpoint and workload telemetry offer another vein of early warnings. EDR tampering or disablement events, suspicious PowerShell or bash execution chains, kernel driver abuse, and unauthorized persistence mechanisms. He urges teams to treat security tooling health as a first-class metric—if agents are offline or quarantined, assume the window for adversary action is open. In containerized environments, he adds, watch for pods running in privileged mode, hostPath mounts, and images pulled from unvetted registries.
Third-party risks have been widely discussed in cybersecurity, but Kajero says “It isn’t just a vendor questionnaire problem,”. He cautioned, “It is an operational challenge where your partners’ weaknesses can become your incident. Organizations should proactively monitor the integrations, such as OAuth scopes, API rate anomalies, unusual data egress patterns, and changes to webhook endpoints. If your supplier pipeline is noisy with deviations, that noise is a signal you cannot ignore.
You also must make it personal. Every integration is a relationship with expectations, boundaries, and regular check-ins. Give each connection a clear owner, a reason for existing, and a review cadence—then actually meet it. It helps to keep a shared incident channel and an escalation path that’s tested, not theoretical.”
Kajero maintains that initial indicators of security breaches are often manifested as nuanced changes in network activity rather than overt alarms. Indicators such as unexpected data transfers to unfamiliar destinations, significant volumes of data movement outside standard operating hours, increased use of encryption or compression, and access attempts from unrecognized identities frequently precede incident disclosure. In payment environments, Kajero emphasizes the critical need for effective segmentation of cardholder data systems and vigilant monitoring for scope expansion, including unidentified assets processing sensitive data or applications incrementally increasing their permissions without notice.
Kajero frames these red flags within a governance model that prizes transparency and actionability. He recommends correlating security signals with business context, which system is critical, which dataset is regulated, and which partner is essential. That context should flow into prioritization, so responders are not chasing low-impact alerts while crown jewels are at risk. He also advocates for runbooks that bind detection to response with clear owners and time-bound SLAs.
“Dashboards should tell a story non-technical leaders can act on,” he added. “If a C-level executive can look at one page and see posture drift, identity anomalies, and vendor exposure trending together, they can authorize the right investments quickly. We win when decisions are faster than attackers, and clarity is how we gain speed.”
To operationalize monitoring at scale, Kajero encourages standardizing reference architectures, including centralized logging with retention aligned to investigation needs, event normalization, and identity-linked telemetry that makes lateral movement visible. He supports purple teaming to validate detections against realistic adversary behaviors, and tabletop exercises that connect technical steps to communications and legal obligations. The output, he says, should be measurable: dwell time reduced, containment faster, recovery assured.
Kajero’s red flag framework serves as an effective guide for security operations. By concentrating on areas such as identity, cloud posture, tool health, third-party integrations, and data movement, and correlating these indicators with business context and established response plans—organizations can enhance their threat detection capabilities. In today’s rapidly evolving threat environment, early identification of key risk factors is critical for timely and effective response.
Kajero brings a practitioner’s lens forged in sectors where risk tolerance is low and regulatory expectations are high—finance, oil and gas, logistics, healthcare, and professional services. He collaborates across GRC, IT Audit, and security teams to translate business requirements into measurable controls, and he is known for operationalizing security with clarity and empathy. His credentials include advanced specialization in vulnerability and cloud security assessments, notably the Qualys Certified Specialist Cloud Security Assessment and Response and the Qualys Certified Specialist Payment Card Information (PCI) Compliance, underscoring his emphasis on continuous control validation.
