Each Monday, the Tenable Exposure Management Academy provides the practical, real-world guidance you need to shift from vulnerability management to exposure management. This week, we look back on some highlights from the first couple of months of posts, including the broad view exposure management provides, business impact and getting to a single pane of glass. You can read the entire Exposure Management Academy series here.Since we started the Exposure Management Academy in March, we’ve covered a range of topics with contributions from many of Tenable’s industry experts. In this post, we look at a few of the highlights, focusing on the work of three Tenable thought leaders: information security engineer Arnie Cabral, CSO Robert Huber and CIO Patricia Grant.Exposure management provides a broader viewIf you’re wondering about exposure management, you should pay attention to Arnie Cabral. He’s on the front lines as we move to exposure management internally. Cabral wrote that Tenable’s shift began with a simple realization.“We knew that, although it is critical to modern cybersecurity, vulnerability management alone doesn’t provide a complete picture of cyber risk,” he wrote. He added that traditional vulnerability management involves scanning assets for known vulnerabilities and remediating them based on severity scores. “However, true security risk management requires a broader view that includes misconfigurations, attack surface visibility and real-time threat intelligence,” he wrote. To get going, he reframed existing policies to align with the new approach. This wasn’t just a matter of editing the text, he noted. “Instead, we redefined our objectives and transformed our policies to ensure alignment with emerging risk-based exposure management frameworks,” he wrote.Read all of Arnie’s post: What it Takes to Start the Exposure Management Journey.It’s all about business impactWith a quarter century in cybersecurity, Robert Huber has the perspective it takes to separate the wheat from the chaff when it comes to risk prioritization.Robert believes that, in the shift to exposure management, you need to start with the right data. “One of the big struggles for security professionals is context switching,” he wrote. “When you meet with your business leaders to update them, you often have to scramble to pull together inputs from a dozen different tools and teams.” He added that data is siloed, often incomplete and nearly impossible to compare. He noted that security professionals need to be able to give CEOs and other leaders a clear, coherent picture of the most acute exposures. But they often struggle to obtain an accurate picture.So, when Tenable started moving to exposure management, Huber ensured that the first step was to assimilate the data. “And I mean all of it,” he wrote. “We combed through tools, platforms and teams for every scrap of data.”He added that, until you bring all that data together, you can’t prioritize.

And we both bring something essential to the table.”She added that exposure management helps keep IT and security teams on track — and they gain a unified view across all assets. “I’m not a fan of ‘swivel-chair security,’” she wrote. “I don’t want my team jumping between tools trying to figure out what to fix first. Exposure management moves us toward a single pane of glass.” According to Patricia, it’s easier to understand what needs to be patched now and what can wait. “That kind of visibility is essential when your infrastructure spans everything from data centers and headquarters to home offices and digital nomads working from just about anywhere,” she wrote.Read all of Patricia’s post: Exposure Management Works When the CIO and CSO Are in Sync
Analysis Summary
# Best Practices: Implementing a Comprehensive Exposure Management Program
## Overview
These practices focus on establishing and maturing an Exposure Management program, designed to provide unified visibility across the entire attack surface (including IT infrastructure, cloud environments, OT/IoT, and identities) to effectively identify, prioritize, and remediate the most acute risks based on potential business impact.
## Key Recommendations
### Immediate Actions
1. **Data Assimilation:** Immediately begin aggregating all security and asset data from disparate tools, platforms, and teams across the organization. This is the foundational step for accurate prioritization.
2. **Establish Data Integration:** Implement connectors (or equivalent mechanisms) to seamlessly combine data from third-party security tools with native sensor data to achieve a unified data set.
3. **Define Shared Accountability:** Formally establish shared accountability between the Chief Information Security Officer (CSO) and the Chief Information Officer (CIO) for cyber risk protection and execution of security strategy.
### Short-term Improvements (1-3 months)
1. **Achieve Unified Visibility:** Focus on migrating away from siloed tools towards a "single pane of glass" solution to eliminate "swivel-chair security" (manual jumping between tools).
2. **Implement Exposure Prioritization:** Begin utilizing consolidated risk signals to prioritize remediation efforts based on the potential business context and likelihood of attack, rather than solely on raw vulnerability scores.
3. **Enhance Cross-Functional Communication:** Develop standardized reporting mechanisms that allow security teams (CSO focus) to clearly communicate prioritized risks, execution needs, and signal interpretation to IT operations teams (CIO focus).
### Long-term Strategy (3+ months)
1. **Mature Security Hygiene:** Establish continuous processes for measuring and improving overall cyber hygiene across all domains (Vulnerability Management, Cloud Security, Identity Exposure).
2. **Incorporate Threat Intelligence:** Integrate real-time threat investigation capabilities with exposure analytics to ensure that prioritization directly reflects currently exploited or highly likely attack paths.
3. **Strategic Risk Communication:** Develop metrics and dashboards capable of accurately communicating the managed cyber risk posture to executive leadership and business stakeholders, aligning security efforts with optimal business performance.
## Implementation Guidance
### For Small Organizations
- **Focus on Consolidation:** Prioritize the immediate selection and deployment of an integrated platform that can ingest data from existing scanning tools (if available) to quickly move beyond spreadsheet management.
- **CIO/CSO Alignment (or Equivalent):** Ensure the IT lead and the security lead (even if one person holds both roles) maintain constant communication to prevent remediation delays due to interpreted security signals.
### For Medium Organizations
- **Connector Implementation:** Actively implement and validate connectors between existing specialty tools (if used) and the central exposure management platform to maximize data ingestion efficiency.
- **Define Remediation Tiers:** Establish clear, defined service level agreements (SLAs) for remediation based on the prioritized risk tiers identified by the unified platform (e.g., "Critical Exposure P1 must be patched within 7 days").
### For Large Enterprises
- **Full Data Ingestion Mapping:** Conduct a comprehensive audit across all technology domains (Data Centers, Cloud, OT/IoT endpoints, Identity providers) to ensure 100% asset visibility is flowing into the central platform.
- **Process Automation:** Leverage exposure management capabilities to automate the creation of remediation tickets for IT teams in their native tools (e.g., ticketing systems), minimizing manual handoffs.
- **Continuous Alignment Review:** Institute quarterly reviews between CIO and CSO leadership specifically focused on the performance of the exposure management program and its impact on operational efficiency and risk posture.
## Configuration Examples
*The provided context focuses on methodology and platform structure (e.g., utilizing connectors, integrating datasets) rather than specific technical configurations like firewall rules or operating system hardening settings.*
**Configuration Focus:** Data Integration Pipeline
1. **Asset Inventory Synchronization:** Configure native sensors (e.g., vulnerability scanners) to push asset information directly to the central Exposure Management Platform API or database.
2. **Third-Party Data Ingestion:** Configure APIs or dedicated connectors to pull data streams from cloud workload protection platforms (CWPP), identity governance tools (CIEM data), and configuration scanners into the unified data lake.
3. **Prioritization Engine Tuning:** Configure business context tags (e.g., "Crown Jewel Asset," "PCI Scope") within the platform to bias remediation prioritization algorithms toward assets deemed most critical to business continuity.
## Compliance Alignment
The principles outlined align with the foundational elements of modern risk-based compliance frameworks:
- **NIST Cybersecurity Framework (CSF):** Strongly supports **Identify** (Asset Management, Risk Assessment) and **Respond** (Mitigation and Remediation planning). Exposure Management directly facilitates evidence for these functions.
- **ISO/IEC 27001:** Supports Annex A.11 (Asset Management) and A.12 (Operations Security) by providing the necessary data continuity and prioritization.
- **CIS Critical Security Controls (CSC):** Directly supports **Control 1 (Inventory and Control of Enterprise Assets)** and **Control 3 (Data Protection)** through comprehensive visibility and focused remediation efforts.
## Common Pitfalls to Avoid
- **Data Silos Persist:** Failing to assimilate *all* relevant data sources; only piecing together partial vulnerability data while ignoring cloud posture or identity risks.
- **Swivel-Chair Security:** Continuing manual processes where security analysts must jump between 5+ distinct consoles to manually determine the next course of action.
- **Ignoring Business Context:** Prioritizing purely based on CVSS scores without factoring in exploitability, asset criticality, and business impact, leading to wasted remediation cycles on low-consequence findings.
- **IT/Security Friction:** Allowing the CSO and CIO relationship to degrade, resulting in security strategy being defined in a vacuum without IT buy-in for execution deadlines and operational load planning.
