National Security Law Firm

In the United States, threats to national security are not tolerated. Individuals, companies, and transactions that are viewed as potential threats are targeted swiftly, aggressively, and with the full authority of federal law. Our National Security lawyers and former agents are available to assist with all national security compliance matters including matters pertaining to national security defense.

Protecting the security of the United States, its citizens, and its businesses is the chief purpose of our country’s law enforcement and military operations. Threats to national security are not tolerated, and the response to national security threats is – and always will be – uncompromising.

For U.S. citizens and businesses, this is a good thing. We must rely on our government to protect us, and we need to feel confident that our borders (both physical and electronic) are secure. However, it can present some practical challenges as well. For companies that engage in business that has national security implications, the aspects of national security compliance can be substantial, and the risks of non-compliance can be severe.

For foreign nationals and businesses that present risks to U.S. national security (or that are perceived as presenting risks to U.S. national security), the risks are also substantial. There are numerous federal laws that proscribe all manner of national security threats, and extradition treaties allow federal authorities to prosecute foreign nationals in the U.S. courts. While this is necessary to the United States’ national security, it presents the risk of extreme deprivation for those charged with national security crimes.

Federal National Security Compliance and National Security Defense Attorneys

Oberheiden P.C. is a federal compliance and national security defense law firm that represents individuals and companies in national security matters. Our Cybercrime and National Security Team is comprised of former U.S. Attorneys, Senior Trial Attorneys with the U.S. Department of Justice (DOJ), and high-ranking agents with the DOJ, Federal Bureau of Investigation (FBI), and other agencies. We have extensive experience counseling clients with regard to compliance in multiple areas related to national security, and we have successfully represented the U.S. government, individuals, and businesses in investigations and trials involving substantial national security implications.

About Our National Security Defense Law Firm

Foreign Corrupt Practices Act (FCPA) Compliance

The Foreign Corrupt Practices Act (FCPA) prohibits individuals and companies from engaging in transactions with foreign privately-owned and sovereign entities that involve bribery and other corrupt practices or practices intended to sew the fabric of corruption. As amended in 1998, the FCPA also applies to foreign nationals and foreign companies that attempt to conduct or facilitate corrupt payments in the United States.

Recently, the DOJ has begun using the FCPA as a tool to target individuals and companies that present national security threats – both in the U.S. and abroad. We advise U.S. based, foreign, and multinational corporations on all aspects of FCPA compliance, and we represent clients in federal investigations involving alleged FCPA violations in the United States and overseas.

Import/Export Compliance

Importers and exporters in various industries can find themselves confronted with issues in the realm of national security, requiring experienced national security defense counsel. From exporting (or re-exporting) proprietary data and technology to importing chemicals and components that can be used to engineer bioweapons or other weapons of mass destruction (WMD), the range of transactions that can trigger federal scrutiny runs the gamut. Frequently, however, seemingly mundane and ordinary imports and exports can garner federal authorities’ attention as well.

We represent domestic and foreign entities with respect to all aspects of import/export compliance. Our lawyers also provide defense representation for matters involving the Office of Foreign Assets Control (OFAC), the U.S. Department of State’s Directorate of Defense Trade Controls (DDTC), the U.S. Department of Commerce’s Bureau of Industry and Security (BIS), U.S. Customs and Border Protection (CBP), and other agencies.

Embargoes and Other Foreign Trade Restrictions

The U.S. government restricts (and, in many cases, prohibits) trade with individuals and entities in various foreign countries. In many cases, these restrictions are tied to concerns about state-sponsored terrorism and other potential threats to U.S. national security. For example, OFAC routinely designates foreign entities as specially designated nationals (SDNs), and it does so without providing notice to the SDN or any domestic businesses doing business with the specially designated national. This frequently leads to unanticipated investigations, and corporations, financial institutions, and other entities must respond to these investigations carefully in order to mitigate the risk of substantial penalties.

Issues involving various other embargoes and trade restrictions can lead to compliance needs, federal investigations, and federal charges as well. At Oberheiden P.C., we help our clients avoid the severe consequences of violating foreign trade restrictions in circumstances that raise national security concerns.

Exon-Florio/FINSA Compliance

Under the Exon-Florio Amendment to the Defense Production Act and Foreign Investment and National Security Act of 2007 (FINSA), foreign investments in U.S. businesses will frequently be subject to review by the Committee on Foreign Investment in the United States (CFIUS) with an eye toward national security considerations. Investments originating from certain foreign nations are particularly likely to garner federal scrutiny, as are investments in assets such as innovative technologies and critical infrastructure. Concerns of corruption, economic espionage, and other illicit and furtive influences can also lead to DOJ, FBI, and other federal agency investigations as well.

Government Contracting

Companies with defense, construction, technology, and other critical government contracts are at high risk for being targeted by foreign agents operating on behalf of businesses, governments, and terrorist organizations. These companies must make cybersecurity and national security compliance top priorities, and they must be prepared to respond immediately in the event of a threat or breach.

Foreign nationals and foreign companies that seek to corruptly influence federal government contractors and that conduct economic espionage can face severe penalties, as can government contractors that engage in corrupt practices (or fail to take appropriate measures to prevent them). In addition to presenting government contractors with regard to all aspects of compliance, we also provide defense representation for national security matters arising out of government contracts.

Anti-Cybercrime Enforcement

At the federal level, anti-cybercrime enforcement and national security often go hand-in-hand. Recently, the DOJ and FBI have placed particular emphasis on targeting economic espionage and corrupt foreign influences from China; however, the DOJ, FBI, and other agencies are also well aware that cybercrime presents national security risks on a global scale. Our practice encompasses the representation of U.S. citizens, foreign nationals, and domestic and international businesses in all matters arising out of the government’s anti-cybercrime enforcement efforts.

Direct and Immediate Threats to National Security

We also represent clients in matters that involve direct and immediate threats to national security. With a team that consists of highly-experienced former federal prosecutors and high-ranking federal agents and a practice that is national in scope, we are able to immediately step in to represent clients that are at risk for prosecution by the DOJ and the U.S. Attorney’s office due to national security-related allegations. If you or your company is being targeted, it is imperative that you engage national security defense counsel right away.
