Propstack is certified according to ISO/IEC 27001:2022, meeting an internationally recognized standard for information security management. The certification confirms that sensitive data is protected through structured processes, continuous risk management, and regular security audits. For real estate companies, this provides independent proof of high security standards and greater transparency when choosing a CRM provider. As a result, information security is an integral part of the Propstack platform and its ongoing development.

Real estate agents process sensitive information every day: contact details of owners and prospects, property documents, purchase and rental interests, communication histories, contract information, and internal company data.

Much of this information converges in one central place: the real estate CRM.

That’s why the range of functions shouldn’t be the only deciding factor when choosing a CRM system. At least as important is the question of how systematically the provider organizes, reviews, and continuously develops information security.

Propstack is certified according to ISO/IEC 27001:2022. This means that Propstack’s information security management has been independently audited against an internationally recognized standard.

What is ISO/IEC 27001?

ISO/IEC 27001 is an internationally recognized standard for information security management systems, or ISMS for short.

An information security management system regulates how a company identifies, assesses, and treats security risks. It’s not just about individual technical protective measures like firewalls or passwords.

The standard takes a holistic view of information security. This includes, among other things:

An ISO 27001 certification therefore doesn’t just mean that individual security functions are present. It confirms that information security is systematically organized within the company and audited based on defined requirements.

Is Propstack ISO 27001 certified?

Yes. Propstack has been certified according to the current standard ISO/IEC 27001:2022.

The certification was carried out by the independent auditing firm A-LIGN Compliance and Security Inc. In addition to Propstack, other companies in the Scout24 Group were certified.

According to Scout24, the audited security standards cover key areas such as product security, network security, and the protection of personal and sensitive information.

What does ISO 27001 certification mean for Propstack customers?

For Propstack customers, the certification makes information security more transparent and verifiable.

1. Information security is systematically managed

The security of your data doesn’t just depend on individual tools or measures. It is backed by defined processes, responsibilities, and control mechanisms.

Potential risks are viewed systematically and security measures are continuously developed.

2. Sensitive information is handled according to defined protection concepts

A real estate CRM processes a large amount of personal and business-critical information.

This includes, for example:

  • Names and contact details
  • Search profiles and property interests
  • Property and owner information
  • Communication histories
  • Documents and agreements
  • Internal sales information
  • Tasks, activities, and process data

The certification confirms that clearly defined security processes exist for the processing, backup, and deletion of sensitive information.

3. Product and network security are continuously monitored

Digital security is not a one-time project. Technologies, attack methods, and potential risks are constantly evolving.

That’s why effective information security management also includes regular reviews of systems, applications, and protective measures.

New products and features at Propstack are developed in protected environments. Systems and cloud applications are continuously reviewed to identify potential vulnerabilities and cyberattacks early on.

4. The certification provides independent proof

Many software providers claim their systems are secure. However, it is often difficult for customers to assess which processes and standards are actually behind them.

ISO 27001 certification provides a more objective benchmark. It confirms that an information security management system has been audited by an independent body based on internationally defined requirements.

For real estate companies, this creates additional security when choosing a CRM provider.

5. Propstack supports real estate companies with their own security requirements

Real estate companies themselves bear responsibility for the careful handling of the data of their customers, employees, and business partners.

The selection of suitable software providers is an important part of this. Especially with a central system like the CRM, companies should check how the provider organizes and proves information security.

Propstack’s ISO 27001 certification can therefore also be a relevant basis for decision-making during internal audits, IT approvals, tenders, or the evaluation of service providers used.

Why is information security particularly important for a real estate CRM?

A modern real estate CRM is much more than a contact database.

It maps the central business processes of a brokerage firm and connects, for example:

  • Contact and lead management
  • Property management
  • Owner and prospect communication
  • Documents and property brochures
  • Viewing organization
  • Sales activities
  • Automations
  • Compliance processes
  • Integrated AI functions

The more central a system is to business operations, the more important the confidentiality, integrity, and availability of the information it contains becomes.

Confidentiality

✓ Only authorized persons should have access to sensitive information.

Integrity

✓ Data should be reliably stored and protected from unauthorized or accidental modification.

Availability

✓ The required information and systems should be available to authorized users when they are needed for business operations.

These three protection goals are among the central principles of information security according to ISO/IEC 27001.

What difference does ISO certification make compared to other CRMs?

Certification doesn’t automatically mean that non-certified software is fundamentally insecure. However, it creates important, independently verified proof.

With a certified provider, customers can see that information security is not represented solely through individual product functions or general security promises. Instead, it is supported by a structured management system, defined responsibilities, and recurring controls.

When choosing a real estate CRM, companies should therefore ask, among other things:

    1. Is the provider certified according to ISO/IEC 27001:2022?
    2. Which products, companies, and locations does the certification cover?
    3. How are security risks identified and treated?
    4. What processes apply to the handling of personal data?
    5. How are product and network security reviewed?
    6. How are access rights and permissions managed?
    7. How does the provider handle security incidents?
    8. Is there reliable evidence or just general security promises?

 

ISO 27001 certification makes the answers to these questions more transparent and easier to compare.

Security as a component of a modern real estate CRM

Brokerage firms should be able to focus on their core business: advising owners, looking after prospects, and successfully marketing properties.

To do this, they need a digital infrastructure they can rely on.

With the ISO/IEC 27001:2022 certification, Propstack emphasizes that information security is an integral part of the platform, the organization, and continuous product development.

Propstack thus combines a powerful real estate CRM with independently audited processes for information security.

The ISO/IEC 27001:2022 certification makes it clear how much importance information security has at Propstack.

For real estate companies, this means: You’re not just using a CRM that supports your daily processes. You’re also choosing a provider whose information security management has been independently audited against an internationally recognized standard.
