Finding Vulnerabilities Is Getting Faster. Keeping Systems Secure Takes Continuous Engineering.

Artificial intelligence is changing how software vulnerabilities are discovered. Security researchers can now identify flaws in complex codebases that might otherwise take considerably longer to detect, giving developers an opportunity to address weaknesses before they are exploited.

In January 2026, AI-powered security research company AISLE identified all 12 vulnerabilities addressed in an OpenSSL security release, including flaws in code that had remained undetected for years. The findings were validated by researchers and disclosed to the OpenSSL project, which coordinated the necessary fixes.

The case illustrates what AI-assisted vulnerability discovery can achieve. But finding a vulnerability does not automatically make a system more secure. It takes engineering expertise to turn that discovery into a tested solution that ultimately reaches production systems.

That work does not end when software is deployed. It continues throughout the product’s lifecycle.

From Vulnerability Discovery to Security Updates

A vulnerability can be discovered by a security researcher, an automated scanning tool, a customer reporting unexpected behavior or an AI-powered system. Whatever the source, identifying the problem is only the beginning.

Engineers first need to establish whether the issue is reproducible, which components and versions are affected, and what consequences it could have. They must then develop a correction and test it against existing functionality.

This validation is particularly important for infrastructure software. A security fix that introduces instability into a load balancer, for example, could affect the applications and services that depend on it.

Once the correction is ready, it must be included in a release, documented and made available to users. The organization operating the software then needs to assess and deploy the update.

Security updates close known vulnerabilities only when the corresponding fixes are applied to the affected systems. Until then, the infrastructure may remain exposed, even if the vendor has already resolved the issue.

The Engineering Work Behind Every Release

Software updates are often perceived as downloadable files or notifications announcing a new version. What users rarely see is the work required to produce them.

At SKUDONET, maintaining the platform involves three specialized areas working together: security engineering, core development, and penetration testing and quality assurance. Each contributes to the continuous effort required to keep the software secure, reliable and capable of meeting evolving infrastructure requirements.

Security Engineering: Monitoring Vulnerabilities and Developing Mitigations

New Common Vulnerabilities and Exposures (CVEs) are regularly disclosed across operating systems, network stacks, cryptographic libraries and other software components.

SKUDONET’s security engineers continuously monitor CVE feeds and security advisories to identify issues that could affect the platform or the applications it protects.

When a vulnerability affects SKUDONET, engineers investigate its impact, develop and validate a correction, and prepare the corresponding security update.

In other situations, particularly when an upstream patch is not yet available or a vulnerability affects an application behind the ADC, the team may develop additional mitigation measures, such as targeted Web Application Firewall (WAF) rules.

These measures can help reduce exposure to known attack vectors while the underlying vulnerability is being addressed.

Core Development: Stability and Product Evolution

Development teams also investigate reported problems, refine traffic-distribution algorithms, improve existing functionality and introduce new capabilities.

For an Application Delivery Controller (ADC), this work spans components responsible for traffic distribution, high availability, TLS processing and application security.

A recent example is SKUDONET Enterprise Edition 10.4.0, which introduced new capabilities for managing network traffic as part of the platform’s ongoing development. Releases like this reflect the work of engineers to evolve the product, maintain its reliability and respond to changing infrastructure requirements.

Penetration Testing and Quality Assurance: Validating Changes Before Release

Developing a correction or a new feature is only part of the process. Before changes reach customers, they must be evaluated to ensure they behave as intended and do not compromise existing functionality.

SKUDONET’s penetration testing and quality assurance teams carry out functional and security testing, performance assessments and stress tests under demanding conditions.

These activities include evaluating high traffic loads, simulated DDoS scenarios, unusual network behavior and potential exploitation attempts.

The objective is to identify weaknesses before deployment and verify that updates preserve the stability, throughput and performance expected from infrastructure responsible for delivering critical applications.

This validation is particularly important when changes affect components operating directly in the flow of production traffic.

Why Direct Access to Engineers Matters

Maintaining a product involves more than publishing new versions. Technical questions and incidents continue to arise as customers adapt their infrastructure, change configurations or encounter unexpected behavior.

When a critical service experiences a problem, response time matters. But so does the expertise of the person handling the incident.

In support structures where requests pass through several departments or escalation levels, valuable time can be spent transferring information before the issue reaches someone with the necessary technical knowledge.

Direct communication with engineers who develop and maintain the product can reduce those intermediate steps. The people investigating the problem already understand the software’s architecture, its components and the technical context behind its behavior.

At SKUDONET, customers with technical support coverage communicate directly with the company’s specialized engineering team. Depending on the contracted service level, assistance can range from ticket-based troubleshooting to remote technical sessions and direct intervention during critical incidents.

A recent example is the response to PHP2Shell, two critical PHP vulnerabilities disclosed in October 2026. Although SKUDONET itself was not directly affected by these vulnerabilities, PHP applications operating behind its load balancer could be exposed.

SKUDONET’s engineering team prepared a WAF ruleset designed to help mitigate known exploitation patterns while customers applied the official PHP security patches.

The ruleset was not a substitute for correcting PHP itself. It provided an additional mitigation measure during the period in which affected applications were being updated.

The technical details are explained in Critical PHP Vulnerabilities: How SKUDONET WAF Helps Mitigate PHP2Shell Attacks.

Cases like this demonstrate why the relationship between software maintenance and technical support matters: responding to an emerging threat can require both product knowledge and the ability to provide practical assistance to customers.

Why Software Security Updates Matter for Critical Infrastructure

An ADC occupies a sensitive position in an organization’s infrastructure. It manages connections between users and applications and may also enforce security policies through capabilities such as a Web Application Firewall.

Its availability can directly affect the services operating behind it.

An outdated ADC does not necessarily become vulnerable immediately. However, when new weaknesses are discovered and corrected, systems that do not receive the corresponding updates may continue running with known security issues.

The consequences depend on the vulnerability and the configuration involved. They can range from unexpected service behavior and availability problems to more serious security exposure.

As AI-assisted tools make vulnerability discovery and analysis faster, attackers may also use these capabilities to identify weaknesses in exposed infrastructure. This adds further pressure on organizations to keep security updates current and reduce the time between the release of a fix and its deployment.

This makes regular maintenance an operational responsibility, not simply a software administration task.

Organizations need to know which versions they are running, assess the relevance of new security advisories, test updates when necessary and establish a process for deploying them.

An active maintenance and support agreement helps preserve access to vendor updates and, where technical assistance is included, the expertise required to investigate complex incidents.

For organizations operating SKUDONET Enterprise Edition, all support plans guarantee access to the latest software updates, security patches, bug fixes, performance improvements, major upgrades, and standard and custom WAF mitigation rulesets throughout the contract period, regardless of the support tier selected.

The difference between support levels lies primarily in the assistance provided. Organizations with sufficient internal expertise may prioritize access to software updates and technical documentation, while those operating business-critical services may require direct engineering assistance, defined response times, remote troubleshooting sessions or 24/7 incident response.

The appropriate level depends on the infrastructure’s criticality, internal expertise and the consequences of a prolonged service interruption.

Keeping Protection Continuous

One aspect of infrastructure maintenance is easy to overlook: the continuity of the agreement that provides access to updates and assistance.

A perpetual software license does not necessarily include indefinite access to new releases or vendor support.

SKUDONET Enterprise Edition, for example, continues operating when its service plan expires. The software does not stop working or become automatically insecure on that date. However, the customer loses access to new versions, security updates and the services included in the expired contract.

The distinction matters. Existing functionality remains available, but newly identified vulnerabilities may no longer receive the corrections needed to address them.

Avoiding an interruption in maintenance coverage should therefore be part of routine infrastructure planning.

While support can be renewed annually, SKUDONET also offers multi-year agreements covering two, three or five years. These options allow organizations to lock in their support costs for the entire contract period, protecting them against inflation-related price increases and future pricing adjustments while reducing the administrative burden of annual renewals.

Longer-term coverage can also help maintain continuity in access to updates and technical resources, while supporting internal security governance and maintenance processes associated with frameworks such as NIS2, PCI DSS and ISO 27001.

At SKUDONET, renewal communications begin 67 days before a service contract expires, giving customers advance notice and time to renew without interrupting their coverage.

The objective is not simply to renew an administrative agreement. It is to prevent an avoidable gap in access to updates and technical resources.

Protecting critical infrastructure doesn’t end when a product is deployed. It’s an ongoing responsibility.
