Frequently asked questions.

Straight answers to the questions buyers actually ask — organised by topic and by the people asking them. From deployment and discovery to Cyber Essentials, identity, network access control and the questions boards care about most.
Deployment

Deployment & getting started

Do we need to install an agent on every device?

No. Rebasoft discovers and inventories assets without requiring agents across your estate. Windows devices use native WMI and PowerShell, reducing deployment effort and operational overhead. Where deeper endpoint visibility is required, an optional lightweight agent is available.

Can we run this on-premises?

Yes. Rebasoft can be deployed on-premises, within a private cloud, or delivered as a managed service. Deployment options are designed to support security, compliance and data residency requirements.

How quickly can we be running?

Most deployments require only a single virtual machine and access to existing data sources. Customers typically see their first asset inventory, service relationships and risk findings within days rather than the months often associated with traditional projects.

Will this work for cloud and containers, or is it network-only?

Yes. Rebasoft provides a unified view across on-premises, cloud and container environments. AWS, Azure, Kubernetes, VMware, Proxmox and Hyper-V assets are continuously discovered and linked to the services they support, helping teams understand risk across the entire technology estate.

What happens if we outgrow Rebasoft?

Rebasoft is designed to scale from small environments to organisations managing hundreds of thousands of assets. Open REST APIs ensure you retain access to your data and can integrate with other platforms whenever required.

How accurate is the asset inventory?

Asset inventories are only valuable if they remain accurate. Rebasoft continuously discovers and validates assets, helping organisations maintain a live inventory rather than relying on periodic scans or manual updates.

Discovery

Asset discovery & inventory

What about Mac, Linux, IoT, BMCs and printers?

Rebasoft is designed to discover and track all IP-addressable assets, including Windows, Linux, macOS, IoT devices, printers, BMCs and network infrastructure. This helps eliminate the blind spots that often create operational and security risk.

We already have ServiceNow / Lansweeper. Why change?

Many organisations use Rebasoft alongside ServiceNow initially. Rebasoft continuously validates asset, service and relationship data, helping keep the CMDB accurate and relevant. Over time, many customers reduce dependence on legacy discovery tools because maintaining multiple overlapping platforms becomes difficult to justify.

Vulnerabilities

Vulnerability management

We already pay for Tenable / Qualys / Rapid7. Why change?

Traditional vulnerability scanners are effective at finding vulnerabilities. The challenge is deciding which findings actually matter. Rebasoft adds business context, asset criticality, exploit intelligence and service relationships to help teams prioritise remediation effort where it will reduce risk most effectively.

We’re a Microsoft shop — won’t Defender do this?

Microsoft Defender provides excellent visibility into Microsoft-managed assets. Most organisations also operate a mix of network infrastructure, Linux systems, cloud platforms, IoT devices, printers and third-party technologies. Rebasoft provides a single view across the entire estate, regardless of vendor.

How do you know which vulnerabilities are actually exploitable?

Rebasoft combines CVE data, CISA Known Exploited Vulnerabilities (KEV), EPSS scoring, vendor advisories and business context to identify vulnerabilities that represent genuine risk. This helps security teams focus on what attackers are most likely to exploit.

Does the team still need to do something every week?

Yes. Security and operations teams still need to take action, but Rebasoft helps reduce thousands of findings into a prioritised list of issues that have the greatest impact on risk reduction and operational resilience.

Will we still see false positives?

Significantly fewer. Where possible, Rebasoft validates vulnerability information against vendor patch data and actual system state, helping reduce the false positives commonly associated with traditional scanning approaches.

How does it handle mobile and BYOD?

Through Microsoft Intune integration, mobile and BYOD devices become part of the same inventory, risk model and reporting framework as the rest of the technology estate.

What about the NVD backlog?

Rebasoft uses multiple authoritative vulnerability intelligence sources, including NVD, CISA KEV, EPSS and vendor advisories. This reduces dependence on any single source and helps ensure emerging threats remain visible even when industry databases experience delays.

Configuration

Secure configuration

How often does Rebasoft re-check configuration?

Configuration posture is continuously assessed against the controls you choose to monitor. When configuration drift occurs, it is identified quickly, allowing teams to remediate issues before they become audit findings or security risks.

Will it tell us how to fix what it finds?

Yes. Findings are linked directly to the configuration settings, policies or controls responsible for the issue, helping teams understand exactly what needs to change and reducing investigation time.

Which frameworks does it cover?

Rebasoft supports Cyber Essentials Plus (CE+), CIS Benchmarks, STIG/DISA, ISO 27001, NIST CSF, PCI DSS, NHS DSPT, DORA and other leading frameworks. A single source of evidence can support multiple compliance initiatives, reducing duplication, effort and audit costs.

Does it work with Intune?

Yes. Rebasoft integrates with Intune to identify non-compliant devices, associate them with users, prioritise risk and track remediation through to resolution.

What about Mac and Linux?

macOS and Linux devices are fully included within asset discovery and visibility workflows. Windows currently has the deepest configuration coverage, with Linux and macOS capabilities continuing to expand.

We already use Drata / Vanta — what’s different?

Platforms such as Drata and Vanta help organisations manage compliance programmes. Rebasoft complements that approach by continuously measuring the actual state of systems and controls, helping ensure compliance evidence reflects operational reality rather than periodic attestations.

Does this replace our patch tool?

No. Rebasoft complements patch management solutions by validating that updates have been successfully applied and identifying where vulnerabilities remain. It helps verify outcomes rather than replace deployment tools.

How quickly will we see the gaps?

Most customers see their initial findings within hours of deployment. Asset visibility, configuration issues and prioritised risks are typically available on the first day.

Cyber Essentials

Cyber Essentials & CE+

Is this Cyber Essentials A7 (User Access Control) evidence?

Yes. Rebasoft continuously evaluates the controls associated with Cyber Essentials User Access Control (A7), including dormant accounts, privileged access and MFA adoption, and can automatically determine compliance status against the published requirements.

Does Rebasoft fill in the Cyber Essentials self-assessment for us?

Yes, where evidence can be collected automatically. Rebasoft pre-populates technical sections of the Cyber Essentials assessment using live system data, reducing manual effort while ensuring answers are supported by evidence.

Does Rebasoft replace our CE+ assessor or submit on our behalf?

No. Certification remains the responsibility of the accredited certification body and the organisation being assessed. Rebasoft simplifies preparation, evidence gathering and ongoing compliance management.

How quickly can we be CE+ ready?

Most organisations gain visibility into their Cyber Essentials Plus readiness within days. Asset inventories, configuration evidence and patch status become available quickly, helping teams prioritise remediation activities.

Does it cover every CE control?

Rebasoft continuously evidences the technical controls required by Cyber Essentials. Policy, governance and organisational controls remain the responsibility of the organisation, but Rebasoft helps ensure technical controls remain aligned with policy.

What about non-Windows devices in scope for CE+?

All IP-addressable devices are included within asset discovery. Windows currently provides the deepest configuration validation, with macOS and Linux coverage continuing to expand.

Is this only for first-time certification, or also for renewal?

Both. Many organisations find the greatest value during renewal because configuration drift often occurs between assessments. Rebasoft helps maintain compliance continuously rather than preparing only at audit time.

We’re tiny — should we just self-certify?

For very small organisations with limited regulatory, contractual or customer requirements, self-certification may be sufficient. Rebasoft is designed for organisations that require greater assurance, visibility and ongoing evidence of compliance.

We’re aiming for ISO 27001 or PCI next. Will this still help?

Yes. The same asset, configuration and control evidence can support multiple frameworks, helping reduce duplicated effort and accelerating future compliance initiatives.

Can MSPs and certification bodies use Rebasoft to deliver CE+ as a service?

Yes. Rebasoft enables MSPs and certification bodies to standardise evidence collection, monitor multiple customers from a single platform and create repeatable compliance and assurance services.

Identity & M365

Identity, Entra & Microsoft 365

Do we need an agent on every server to see local admins?

No. Rebasoft uses native operating system capabilities and existing credentials to identify local administrators and privileged accounts without requiring an agent on every server.

What level of Entra ID licensing do we need?

Rebasoft works with Entra ID Free, P1 and P2 licensing tiers. Where advanced Microsoft APIs are available, they are used automatically to improve efficiency without affecting evidence quality.

Will this slow down our domain controllers?

No. Data collection is designed for production environments and uses efficient, incremental collection methods that minimise operational impact.

Does this replace SailPoint or Saviynt?

For many SME and mid-market organisations, Rebasoft can provide the visibility and evidence needed without the complexity of a dedicated IGA platform. Larger enterprises may choose to use Rebasoft alongside SailPoint or Saviynt to provide additional operational context and validation.

How quickly will we see Microsoft 365 results?

Most organisations gain useful insights within hours. Common early findings include unnecessary licence spend, excessive privileged access, dormant accounts and MFA gaps that can be addressed immediately.

Does Rebasoft change anything in our tenant?

No. Rebasoft operates in read-only mode by default. It provides visibility, evidence and recommendations without making changes to your Microsoft 365 environment.

What about Exchange Online, Teams, SharePoint, OneDrive and Azure RBAC?

These areas are not currently collected by Rebasoft. We believe transparency is important, so we clearly distinguish between available functionality and roadmap capabilities. Today, Exchange Online mailbox delegation, Teams channel membership, SharePoint and OneDrive sharing permissions, and Azure resource-level RBAC are on the roadmap rather than available now — talk to us about timing if any are blocking.

Does this work alongside Defender for Cloud Apps / Defender for Identity?

Yes. Microsoft Defender focuses on detecting and responding to threats. Rebasoft focuses on understanding assets, identities, relationships and control effectiveness. Together they provide a more complete picture of both exposure and active threats.

Network & NAC

Network discovery & NAC

Do we need to install agents or supplicants?

No. Rebasoft uses existing network protocols and telemetry to discover, monitor and control devices without deploying agents, supplicants or additional endpoint software.

Will we have to re-engineer our network or buy appliances?

No. Rebasoft is designed to work with existing network infrastructure, reducing deployment complexity and avoiding the cost and risk associated with inline appliances.

How does the NAC decide what’s allowed on?

Rather than relying solely on device identity, Rebasoft evaluates device behaviour. Network traffic patterns, communication activity and policy conformance help determine whether a device should remain connected, be restricted or be quarantined.

Does our network kit support NetFlow?

Most enterprise-grade switches, routers and firewalls support NetFlow, IPFIX, sFlow or jFlow. During onboarding, Rebasoft confirms what telemetry is already available and identifies any gaps.

What about IoT and other non-user devices?

Yes. IoT, OT and unmanaged devices are often the biggest visibility challenge for security teams. Rebasoft discovers and monitors these devices without requiring agents or manual maintenance of device inventories.

Does this replace our network monitoring tool?

In many environments, yes. Rebasoft combines asset discovery, traffic visibility, performance monitoring, configuration management and access control within a single platform, reducing the need for multiple standalone tools.

For the board

For executives & boards

How do I know my security controls are actually working?

Most organisations assume controls are working because they were deployed at some point in the past. Rebasoft continuously validates the controls protecting your assets, users, applications and services, helping you identify failures, drift and exposure before they become incidents.

What could hurt our business most today?

Rebasoft identifies the assets, users, vulnerabilities and control failures that present the greatest risk to critical business services, helping leadership focus attention where it matters most.

If we suffered a breach tomorrow, what would be affected?

Rebasoft maps relationships between assets, users, services and vulnerabilities, helping organisations understand potential attack paths and blast radius before an incident occurs.

Can leadership trust the data being reported?

Rebasoft continuously discovers and validates assets directly from the environment, reducing dependence on manual updates, spreadsheets and disconnected systems.

For the CIO

For CIOs

Why do organisations buy Rebasoft?

Most organisations already own multiple security and operational tools. The problem is not a lack of data — it is that nobody can confidently answer:

  • What do we own?
  • What supports critical services?
  • What is exposed?
  • Are our controls working?
  • Can we prove it?

Rebasoft helps answer those questions continuously.

Why is this important now?

Boards, insurers, auditors and regulators increasingly expect organisations to prove control effectiveness continuously rather than periodically. Point-in-time assessments are no longer sufficient.

How does Rebasoft reduce operational costs?

By replacing manual asset management, reducing audit preparation effort, improving remediation prioritisation and consolidating multiple overlapping tools.

What return on investment should we expect?

Most customers realise value through:

  • Reduced tool sprawl
  • Reduced audit effort
  • Faster remediation
  • Better utilisation of existing security investments
  • Fewer unknown assets
  • Improved compliance outcomes
For the CISO

For CISOs

What makes Rebasoft different from vulnerability scanners?

Vulnerability scanners tell you what vulnerabilities exist. Rebasoft helps you understand:

  • Which matter
  • Which are exploitable
  • Which affect critical services
  • Which should be fixed first
What makes Rebasoft different from CAASM platforms?

Most CAASM platforms aggregate information from other tools. Rebasoft continuously discovers and validates assets directly from the environment while also providing vulnerability, configuration, traffic and compliance intelligence from the same platform.

How does Rebasoft reduce attack surface?

By identifying unmanaged assets, vulnerable systems, insecure configurations, excessive access and exposed services before attackers find them.

How does Rebasoft support Zero Trust?

Rebasoft continuously validates assets, users, identities, configurations and device behaviour, helping organisations implement and maintain Zero Trust principles.

Compliance & risk

Compliance, risk & why Rebasoft

Can Rebasoft help us prepare for cyber insurance renewal?

Yes. Rebasoft provides evidence of asset visibility, vulnerability management, configuration management, access control and control effectiveness that insurers increasingly expect to see.

How does Rebasoft help with Cyber Essentials Plus?

Rather than preparing once a year, Rebasoft continuously measures compliance, helping organisations remain ready throughout the year.

How does Rebasoft help with ISO 27001?

Rebasoft provides continuous evidence for many technical controls, reducing manual evidence gathering and helping organisations maintain audit readiness.

Can Rebasoft support DORA and NIS2?

Yes. Both frameworks require organisations to understand assets, services, dependencies, risks and controls. Rebasoft provides continuous visibility into each of these areas.

Why Rebasoft instead of buying another tool?

Most organisations do not have a tool problem — they have a visibility problem. They cannot confidently answer:

  • What assets exist?
  • What supports critical services?
  • What is vulnerable?
  • What is misconfigured?
  • What is communicating?
  • What is exposed?
  • Are controls working?

Traditional tools answer one part of that problem. Rebasoft connects the whole picture — continuously discovering assets, mapping relationships, validating controls, prioritising risk and providing the evidence needed by operations, security, compliance and leadership teams from a single platform.

What happens if we do nothing?

Risk continues to grow silently. Assets change, users change, services change, vulnerabilities change, controls drift and attackers adapt. The longer organisations rely on periodic scans, spreadsheets and disconnected tools, the harder it becomes to understand what is actually happening inside the environment.

Rebasoft was built to replace assumptions with continuous visibility and evidence.
