Future-ready cyber defense for remote businesses in 2025

‍

In 2022, LastPass detected suspicious activity in their development environment, where hackers gained unauthorized access to portions of their source code and technical information. By November, the attackers exploited this stolen data to breach a third-party cloud storage service.

In March 2023, hackers exploited vulnerabilities in a senior DevOps engineer's home setup, using keylogger malware to bypass multifactor authentication and access the LastPass corporate vault.

Such incidents demonstrate that with the adoption of flexible work, remote-first enterprises face heightened risks, including unsecured home networks, shadow IT, and advanced phishing schemes.

A single compromised endpoint or weak policy enforcement can lead to widespread data breaches, operational disruptions, and reputational harm.

In this context, proactive cyber defense strategies are essential for securing remote-first enterprises. Let's dive into practical strategies and tools remote-first companies can use to safeguard their operations.

The need for cyber defense in remote-first companies

According to the FBI, cyberattacks targeting remote workers have surged 400% since the pandemic, while cloud-based services have seen a 238% increase in attacks.

Here are the four critical challenges for remote-first companies:

1. Changing threat landscape

Since the pandemic, the increase in online communication led to a surge in cyberattacks. The FBI’s IC3 reported a 300% increase in cybercrimes during this period, and scammers targeting remote employees.

In 2023, Okta experienced a data breach affecting several customers. Hackers exploited stolen credentials of a service account stored in Okta's customer support system.

The breach occurred when an Okta employee logged into the service account after signing into their personal Google profile on an Okta-managed laptop.

This allowed the hackers to impersonate staff and hijack legitimate Okta sessions for affected customers.

2. Rise of ransomware and phishing

Often, remote workers become victims of social engineering schemes and targeted phishing. Hackers use phishing, RDP weaknesses, and software vulnerabilities to execute ransomware attacks.

In May 2021, the Colonial Pipeline, a critical fuel supplier for the U.S. East Coast, experienced a ransomware attack. Hackers accessed Colonial's network through a disused VPN account used by an employee, which lacked multi-factor authentication.

Hackers stole nearly 100 GB of sensitive data and deployed ransomware to encrypt critical company data, disrupting operations.

The company identified the attack early and took parts of its system offline, including shutting down 5,500 miles of pipeline operations to contain the threat.

3. Decentralized IT infrastructure

Using personal devices and diverse cloud services complicates security for remote-first companies. Since 2022, 31% of all workers worldwide are remote, and organizations are increasingly adopting cloud technologies to ensure business continuity.

In December 2022, Slack detected unauthorized access to a subset of its externally hosted GitHub repositories.

Slack swiftly invalidated stolen employee tokens, investigated the incident, and ensured no customer data or primary codebase was impacted.

Slack’s rapid response demonstrates the importance of robust monitoring and collaborative security measures for securing decentralized infrastructures.

4. Regulatory compliance risks

Stricter regulations like GDPR and CCPA demand robust cyber defense measures to avoid penalties.

In 2023, Sephora was fined $1.2M under the California Consumer Privacy Act (CCPA) for failing to comply with key regulatory requirements.

Sephora allowed third-party trackers to collect personal data from users, such as geolocation and shopping cart details, in exchange for targeted advertising and analytics services.

However, the company did not disclose this data-sharing practice to consumers or honor opt-out requests configured through privacy settings. This case underscores the importance of adhering to regulatory standards.

Failing to secure distributed networks increases the risk of data breaches and exposes remote enterprises to legal penalties and compliance costs.

6 proactive strategies for remote-first enterprises

Adopting robust defense measures can protect distributed networks from costly disruptions. With the global VoIP services market projected to grow from $158.72 billion in 2024 to $361.53 billion by 2031, the demand for secure and scalable remote communication is greater.

Here are six essential strategies remote-first organizations may adopt:

1. Secure remote access with VPN alternatives

Traditional VPNs lack the scalability and security needed for modern remote enterprises. Adopting solutions like Zero Trust Network Access (ZTNA) or Secure Access Service Edge (SASE) ensures that only authenticated users and devices can access company resources.

Gartner predicts that by 2025, 65% of organizations using SASE components will consolidate them into unified, single-vendor solutions, compared to just 15% in 2022.

This underscores the importance of integrated cyber defense solutions.

2. Multi-factor authentication (MFA)

Mandating MFA for all systems and applications adds a critical layer of security, reducing credential-based attacks.

In 2023, Akira ransomware threat actors targeted Cisco VPNs that lacked MFA, exploiting this gap to infiltrate organizations. Without MFA, these VPNs became vulnerable to brute force attacks, enabling attackers to gain unauthorized access.

Cisco later issued an advisory and patch for vulnerabilities in their Adaptive Security Appliance (ASA) Software and Firepower Threat Defense (FTD) to address these risks.

3. Cybersecurity awareness training

Human error remains a critical vulnerability in cybersecurity, with 74% of all breaches involving the human element.

Regular training sessions can equip employees to identify phishing emails, malware, and social engineering attacks. However, under pressure or when an email appears from a trusted source, such as the CEO, employees may still click on malicious links, underscoring the importance of continuous education.

4. Device management policies

As remote employees use personal devices for work, enforcing Bring Your Own Device (BYOD) policies and deploying Mobile Device Management (MDM) solutions is critical.

MDM tools enable IT teams to enforce security updates, remotely wipe lost devices, and manage app permissions. Ensure secure access to your platform across employees' personal and company devices, and strengthen your cyber defense.

5. Cloud security optimization

As remote enterprises rely heavily on cloud environments, workload isolation, and access controls are essential. Cloud Access Security Brokers (CASB) provide visibility into sanctioned and unsanctioned cloud applications, enabling enterprises to monitor shadow IT effectively.

CASBs also enforce robust data loss prevention measures, limit access based on employee status or location, and identify unusual activity.

6. Regular penetration testing

Simulating cyberattacks helps identify vulnerabilities in remote work setups and equips employees to prevent online scams.

In 2024, a faulty software update from CrowdStrike led to a global IT outage, affecting 8.5 million Windows systems and causing operational disruptions.

The root cause was identified as a flaw in the Rapid Release Content configuration template, which was not detected due to inadequate testing processes. A content validator tool failed to identify the flaw before deployment.

Robust testing protocols, including canary deployments and risk assessments, are essential to minimizing the risk of widespread disruptions.

Technologies enhancing cyber defense in remote-first enterprises

In July 2024, the Qilin ransomware group stole credentials stored in Google Chrome and exploited networks without multi-factor authentication. They used a PowerShell script to extract login credentials, amplifying the damage beyond ransomware encryption.

To counter evolving cyber threats, enterprises must adopt cutting-edge technologies, including AI and machine learning, to bolster their defenses.

Here are five critical technologies reshaping cyber defense:

1. AI-powered threat detection

AI can detect threats faster and more precisely. AI algorithms analyze vast datasets to identify anomalies and detect patterns of malicious behavior in real time.

IBM report highlights that organizations using AI-powered security solutions and automation save an average of $2.22 million in data breach costs compared to those without such technologies. AI is the backbone of modern cyber defense strategies.

2. Secure collaboration tools

Platforms like Rocket.Chat offer an encrypted messaging app that features role-based access control, ensuring secure team collaboration in remote-first environments.

For instance, the NATO CCDCOE uses Rocket.Chat for encrypted communication among its members, safeguarding classified data.

3. Advanced endpoint protection

Secure your devices beyond the office perimeter. Next-generation antivirus and behavioral analytics tools can detect threats like fileless malware and insider attacks. Microsoft Defender for Endpoint, for example, can identify and respond to endpoint vulnerabilities.

4. Incident response automation

Did you know automated playbooks can help respond to security incidents effectively? You can reduce response times and human errors. Platforms like Palo Alto Networks’ Cortex XSOAR offer integrated automation, allowing teams to triage, investigate, and resolve incidents quickly.

5. Cloud Access Security Brokers (CASB)

CASBs provide critical visibility into shadow IT, enforce compliance, and mitigate threats across cloud services.

With Gartner estimating that over 95% of new digital workloads will be deployed on cloud-native platforms by 2025, adopting CASBs is ideal for securing cloud environments.
