Scott Heider is a manager within the Cisco Security Visibility and Incident Command team that reports to the company’s Security & Trust Organization. Primarily tasked with helping to keep the integration of an acquired company’s solutions as efficient as possible, Heider and his team are typically brought into the process after a public announcement of the acquisition has already been made. This blog is the final in a series focused on M&A cybersecurity, following Dan Burke’s post on Making Merger and Acquisition Cybersecurity More Manageable.
Mergers and acquisitions (M&A) are complicated. Many factors are involved, ensuring cybersecurity across the entire ecosystem as an organization integrates a newly acquired company’s products and solutions—and personnel—into its workstreams.
Through decades of acquisitions, Cisco has gained expertise and experience to make its M&A efforts seamless and successful. This success is in large part to a variety of internal teams that keep cybersecurity top of mind throughout the implementation and integration process.
“Priority one for the team,” says Heider, “is to balance the enablement of business innovation with the protection of Cisco’s information and systems. Because Cisco is now the ultimate responsible party of that acquisition, we make sure that the acquisition adheres to a minimum level of security policy standards and guidelines.”
The team looks at the acquired company’s security posture and then partners with the company to educate and influence them to take necessary actions to achieve Cisco’s security baseline.
That process starts with assessing the acquired company’s infrastructure to identify and rate attack surfaces and threats. Heider asks questions that help identify issues around what he calls the four pillars of security, monitoring, and incident response:
The infrastructure that Heider’s team evaluates isn’t just the company’s servers and data center infrastructure. It can also include the systems the acquisition rents data center space to or public cloud infrastructure. Those considerations further complicate security and must be assessed for threats and vulnerabilities.
Once Heider’s team is activated, they partner with the acquired company and meet with them regularly to suggest areas where that acquisition can improve its security posture and reduce the overall risk to Cisco.
Identifying and addressing risk is critical for both sides of the table, however, not just for Cisco. “A lot of acquisitions don’t realize that when Cisco acquires a company, that organization suddenly has a bigger target on its back,” says Heider. “Threat actors will often look at who Cisco is acquiring, and they might know that that company’s security posture isn’t adequate—because a lot of times these acquisitions are just focused on their go-to-market strategy.”
Those security vulnerabilities can become easy entry points for threat actors to gain access to Cisco’s systems and data. That’s why Heider works so closely with acquisitions to gain visibility into the company’s environment to reduce those security threats. Some companies are more focused on security than others, and it’s up to Heider’s team to figure out what each acquisition needs.
“The acquisition might not have an established forensics program, for instance, and that’s where Cisco can come in and help out,” Heider says. “They might not have tools like Stealthwatch or NetFlow monitoring, or Firepower for IDS/IPS operations.”
When Heider’s team can bring in their established toolset and experienced personnel, “that’s where the relationship between my team and that acquisition grows because they see we can provide things that they just never thought about, or that they don’t have at their disposal,” he says.
One of the most important factors in a successful acquisition, according to Heider, is to develop a true partnership with the acquired company and work with the new personnel to reduce risk as efficiently as possible—but without major disruption.
Cisco acquires companies to expand its solution offerings to customers, so disrupting an acquisition’s infrastructure or workflow would only slow down its integration. “We don’t want to disrupt that acquisition’s processes. We don’t want to disrupt their people. We don’t want to disrupt the technology,” says Heider. “What we want to do is be a complement to that acquisition, – that approach is an evolution, not a revolution.”
The focus on evolution can sometimes result in a long process, but along the way, the teams come to trust each other and work together. “They know their environment better than we do. They often know what works—so we try to learn from them. And that’s where constant discussion, constant partnership with them helps them know that we are not a threat, we’re an ally,” says Heider. “My team can’t be everywhere. And that’s where we need these acquisitions to be the eyes and ears of specific areas of Cisco’s infrastructure.”
Training is another way Heider, and his team help acquisitions get up to speed on Cisco’s security standards. “Training is one of the top priorities within our commitments to both Cisco and the industry,” Heider says. “That includes training in Cisco technologies, but also making sure that these individuals are able to connect with other security professionals at conferences and other industry events.”
When asked what advice he has for enterprises that want to maintain security while acquiring other companies, Heider has a few recommendations.
Having the right security agents and clear visibility into endpoints is critical. As is inputting the data logs of those endpoints into a security event and incident management (SEIM) system. That way, explains Heider, you have visibility into your endpoints and can run plays against those logs to identify security threats. “We’ll reach out to the asset owner and say they might have malware on their system—which is something nobody wants to hear,” says Heider. “But that’s what the job entails.”
Often, end users don’t know that they’re clicking on something that could have malware on it. Heider says user education is almost as important as visibility into endpoints. “Cisco really believes in training our users to be custodians of security, because they’re safeguarding our assets and our customers’ data as well.”
End users should be educated about practices such as creating strong passwords and not reusing passwords across different applications. Multi-factor authentication is a good practice, and end users should become familiar with the guidelines around it.
Updating software and systems is a never-ending job, but it’s crucial for keeping infrastructure operating. Sometimes, updating a system can weaken security and create vulnerabilities. Enterprises must maintain a balance between enabling business innovation and keeping systems and data secure. Patching systems can be challenging but neglecting the task can also allow threat actors into a vulnerable system.
Heider says public cloud operations can be beneficial because you’re transferring ownership liability operations to a third party, like Amazon Web Services or Google Cloud platform. “The only caveat,” he says, “is to make sure you understand that environment before you go and put your customer’s data on it. You might make one false click and expose your certificates to the Internet.”
Heider says that while a big part of his job is helping acquisitions uplevel their security domain to meet baseline security requirements, there’s always the goal to do even better. “We don’t want to be just that baseline,” he says. His team has learned from acquisitions in the past and taken some of those functionalities and technologies back to the product groups to make improvements across Cisco’s solutions portfolio.
“We’re customer zero – Cisco is Cisco’s premier customer,” says Heider, “because we will take a product or technology into our environment, identify any gaps, and then circle back to product engineering to improve upon it for us and our customers.”

Dan Burke is the director of strategy, risk, and compliance for AppDynamics, a company acquired by Cisco in 2017. Burke and his team are a vital part of the Cisco acquisition process in helping acquired companies adhere to a higher level of cybersecurity. This blog is the fourth in a series focused on M&A cybersecurity, following Shiva Persaud’s post on When It Comes to M&A, Security Is a Journey.
Part of the secret to Cisco’s success is its ability to acquire companies that strengthen its technology portfolio and securely integrate them into the larger organization. From the outside, that process might appear seamless—consider Webex or Duo Security, for instance—but a fruitful acquisition takes tremendous work by multiple cross-functional teams, mainly to ensure the acquired company’s solutions and products meet Cisco’s rigorous security requirements.
“My team is responsible for aligning new acquisitions to Cisco controls to maintain our compliance with SOC2 and FedRAMP, as well as other required certifications,” says Burke.
When Cisco acquires a new company, it conducts an assessment and produces a security readiness plan (SRP) document. The SRP details the identified weaknesses and risks within that company and what they need to fix to meet Cisco standards.
“In the past, my team wouldn’t find out about an acquisition until they received a completed SRP. The downside of this approach was that the assessments and negotiations had been done without input from our group of experts, and target dates for resolution had already been decided on,” shares Burke.
“We needed to be involved in the process before the SRP was created to understand all risks and compliance issues in advance. Now we have a partnership with the Cisco Security and Trust M&A team and know about an acquisition months before we can start working to address risks and other issues—before the SRP is completed and the due dates have been assigned,” Burke adds.
“Another issue resolved in this process change is that Cisco can gain earlier access to the people in the acquired company who know the security risks of their solutions. During acquisitions, people will often leave the company, taking with them their institutional knowledge, resulting in Cisco having to start from scratch to identify and assess the risks and determine how best to resolve them as quickly as possible,” says Burke. “It could be vulnerabilities in physical infrastructure or software code or both. It could be that the company isn’t scanning often enough, or they don’t have SOC 2 or FedRAMP certification yet—or they’re not using Cisco’s tools.”
“Third-party vendors and suppliers can also present an issue,” he adds. “One of the biggest risk areas of any company is outside vendors who have access to a company’s data. It’s vital to identify who these vendors are and understand the level of access they have to data and applications. The earlier we know all these things, the more time we must devise solutions to solve them.”
“Now that I’m in the process earlier, I can build a relationship with the people who have the security knowledge—before they leave. If I can understand their mindset and how all these issues came about, I can help them assimilate more easily into the bigger Cisco family,” says Burke.
The additional benefits of bringing teams in earlier are reduced risk and compliance requirements can be met earlier. It also provides a smoother transition for the company being acquired and ensures they meet the security requirements that customers expect when using their technology solutions.
“Without that early involvement, we might treat a low-risk issue as high risk, or vice versa. The misclassification of risk is extremely dangerous. If you’re treating something as high risk, that’s low risk, and you’re wasting people’s time and money. But if something’s high risk and you’re treating it as low risk, then you’re in danger of harming your company,” Burke shares.
“The key is to involve their risk, compliance, and security professionals from the beginning. I think other companies keep the M&A process so closely guarded, to their detriment. I understand the need for privacy and to make sure deals are confidential but bringing us in earlier was an advantage for the M&A team and us,” Burke adds.
When asked what he thinks makes Cisco successful in M&A, Burke says, “Cisco does an excellent job of assimilating everyone into the larger organization. I have worked at other companies where they kept their acquisitions separate, which means you have people operating separately with different controls for different companies. That’s not only a financial burden but also a compliance headache.”
“That’s why Cisco tries to drive all its acquisitions through our main programs and controls. It makes life easier for everyone in terms of compliance. With Cisco, you have that security confidence knowing that all these companies are brought up to their already very high standards, and you can rely on the fact that they don’t treat them separately. And when an acquisition has vulnerabilities, we identify them, set out a remediation path, and manage the process until those risks are resolved,” Burke concludes.
